[@carlmazziotti221]

Since you sound like you know your stuff I'm hoping I can run a question by you. I have a 07 Shelby GT500. When I push the RPM's beyond 4000 the entire electrical system power cycles. Dash lights, stereo... The engine continues to run but everything else cycles. It will even occur at a standstill rev. It doesn't appear to be a ground issue so I was wondering if it could be a regulator issue within my alternator. I read that ford had issues with that year due to the high RPM's. Do you think it could be an alternator issue, or am I perhaps barking up the wrong tree. I'd hate to drop $600 on a new alternator only to learn it wasn't the issue. BTW, I also read that many people had to upgrade the alternative wiring so perhaps that's the problem. I've had a really hard time finding someone skilled enough to share an opinion that I could really trust. Any advice you might be able to share would be helpful.

I have narrowed it down to a possible alternator issue. No one has been able to explain a total power cycle in any of the ford GT500 forums.

The voltage sense wire is exactly what it says on the tin. It senses the voltage at whatever you connect it to without applying any additional load. Because there is no load on the sense wire, there is almost zero voltage drop across the sense wire, meaning you get an accurate voltage for the regulator to work from. If it were me, I'd be running the ECU and Ignition from a buss bar and connecting the sense wire to that.

[@TdrSld]

Rob sound like you have 1/3 of the charging system done. A lot of people talk about the "BIG 3" wire upgrade, but it's really needing to be the "BIG 4". First is the Battery to Alt wire at least 4g for something under 150 amp, I find 00g to be the best catch all sub 500amps. The Alt. needs to feeding the battery directly, so don't take it the start as you have it now, give the starter it's own cable straight from the battery/bus bar. Second is the chassis ground, again 4g is the starting gauge I like but normally do a 0g minimal sub 500amps. Third is the engine ground, I live be the rule, one ground per side of the block. I always use 0g for ground sub 500amp. The Fourth and most important is grounding the back of the Alt directly to the chassis or battery (I prefer chassis as it can eat up noise from the coils), I normally run 4g sub 150amp and 0g for sub 500amp. Alt's ground through the side of the case that the rectifier is on and through the mounting point (almost always the front of the case), this means the ground is just going through the small solid case bolts holding the two halves together. DC likes a lot of smaller wires working to gather for lest Voltage drop, as DC travels along the out side of the wire, so more strands in a give gauge of wire, the more surface area for the DC to travel along. Hope this helps solves some of the voltage drop off problems you have.

[@gordowg1wg145]

Very cool video. The custom etching not only looks super cool but, if it should go 'missing', it will be easy to identify as yours. Heck, it may even dissuade the bad people in the first place. I'd just add one point - check the voltage between the alternator housing and the battery/chassis. Some vehicles use insulators to protect the alternator against vibration and sometimes the alternator ground wire isn't up to the job - I've seen them get so hot they've melted the insulation on them. I would normally use around an 0 gauge for the alternator ground and the alt' to battery cable, but I've been using lower current values - stepping up a size (or two) may be a good idea to minimise voltage drop with such high current values. Oh, there's still a lot of confusion about the 'power' the alternator takes from the engine - a higher current rated alternator doesn't take more 'power' from the engine than a lower rated one IF the current being used by the vehicle is the same - might even be more efficient and take less. Alternators only draw enough 'power' to maintain a set voltage against the electrical load, a larger one doesn't automatically take more because it's larger.

[@Marko343]

I think a lot of us learned a bunch of new info from this guy. Seems like a awesome company.

[@ericschumacher5189]

@Rob Dahm I understand this alternator will address some of the issues high current issues you observed (like the fan), though I was wondering if you‘VE considered possibly adding some large capacitors to these specific high draw circuits? I don’t have much experience with this, but I know cars with serious audio system (like purpose built audio competition vehicles) sometimes have a capacitor to pad the huge Intermittent draw of the amps / subwoofer, etc....looking into these could be helpful in keeping voltage more constant as these high draw circuits / components turn on / off on the 4-rotor. Keep up the good work!!!

[@matthewf1979]

Mechman is another great US made high current alternator company. I believe their highest current “Stock” alternator is 400 amps. Of course that’s not at idle, same with DC power alternators.

[@sunyun4425]

Semiconductor switching devices produce significant harmonic voltages as they abruptly chop voltage waveforms during their transition between conducting and cutoff states. Inverter circuits are notorious for producing harmonics, and are in widespread use today. An adjustable-speed motor drive is one application that makes use of inverter circuits, often using pulse width modulation (PWM) synthesis to produce the AC output voltage. Various synthesis methods produce different harmonic spectra. Regardless of the method used to produce an AC output voltage from a DC input voltage, harmonics will be present on both sides of the inverter and must often be mitigated.

[@blkdna748]

Wow that's kool am new to this company and advantages of efficient alternators.Its amps at high rpm nd idle. Brillant! They are alternator tuners. Awsome

[@ben94cobra]

interesting that he recommends picking up the sense right off the output. I've found that running a "remote sense" nearer to the load side of the system shows a significant drop in voltage and allows the internal regulator to pump out more volts. We will then see ~13.8-14v on the load side and 14.4-14.6v on the alternator output. This is from full re-wires building my own harnesses and integrating with standalone ECUs etc.

[@elliott1787]

Especially when Rob mentioned having lights on potentially causing voltage drop at the ignition. Switched side of the main fusebox is ideal. Granted, his power wire is likely going to be far oversized and he won't have to worry that much.

Many old drag cars had no battery, many sprint cars today have no battery, they rink magneto ignition/distributors that are self powered, they generate their own voltage and energy with a small generator inside the distributor. That's why you notice then push starting sprint cars when they stall on the track

[@casemodder89]

I'd bridge the sense wire to battery positive. Bcs you want 14,7 at the BATTERY to charge it sufficiently. Run big wires positive from alt to battery, battery to fusebox + starter. Negative from engine block or bracket that attaches to the alt and bolt it down to a strong bar/tube on the chassis. And the voltage drop on upshifts results from dropping engine + alternator RPM's. the field current is set to put out for ex. 14,7V @ 12000 alternator RPM's. After upshift the RPM's drop to like 8000 and the regulator has to adjust the field current higher to suit it for lower RPM's @ still 14,7V. That reaction takes some time. Best way to filter these dips is a LiFePo4 battery of around 20Ah for a lead acid /AGM delete. But LiFePo4 batteries cant take more then 14,6 volts short periods or 14,4V long term. There are even ready made high quality LiFePo4 starter batteries in a carbon fiber case wit bluetooth disabeling/enabeling, external emergency cut of wire from company called LiteBlox @LiteBlox .

I would love to see how your car will do on the dyno with this new alternator.

[@johngy6296]

At higher RPMs, with a loaded, standard wound alternator, it reaches its knee point where pushing it harder/faster causes saturation - voltage and current distort very quickly as the magnetic field is unable to support the load. Just as increasing voltage beyond an electrical motor capacity won’t make it spin faster, it just gets hotter and causes a loss of torque. It’s not exactly a mechanical problem, it’s a magnetic-electrical problem. Increasing the alternator current capacity may improve the issue, but it won’t fix it. A custom wound alternator allowing a greater operating range will better improve the problem however, you will end up with a lot lower current capacity at idle. This is why higher revving engines often have higher voltage electrical systems, so the alternator can still support say 150 amps at idle.

[@Barty.Crowell]

There are batteries that actually run both 12/16V where you only need the regular 12v charging system but connect the 16v side to the starter so it spins faster and helps start the engine faster. The guys over at Team boosted used one in their one rotor roadster (those guys are fans of yours)

Rob, I posted links for you on this subject. If you don't think it's relevant, consider the keywords mentioned, 3rd harmonic is most significant. Well your engine fires 3 times per rotor revolution. Other keywords, rectifiers(alternator), transformer(ignition coil), capacitors(msd boxes and cabling), generators(alternator), DC supply rails etc. Your probably thinking I'm nuts but I'm not joking. You might have to break out an oscilloscope or contact a lead engineer at MSD for assistance. Solution might be simple as installing some filters, mods to your casebook cablingand grounding. But your engine has alot going on electrically compared to the average piston engine. Also rotary engines are notorious for particularly powerful "harmonics"at high rpms which have been known to "sheer housing bolts"
