Yes it's Tuesday! Well, in Australia and New Zealand it is:) So it's time for another dose of Tech Tuesday! Need to make room for engine mods or get better weight distribution ? It's time to move that battery! Before you grab a grinder and start ripping your battery out from its original spot though, there are a few things you need to know. Luckily Tuning Fork is here to tell us how it's done:)

Yes bigger is better when it comes to batteries, I totally agree! It's pretty much the best insurance you can buy against alternator failure. Several months ago I went to Nashville TN to get car parts. As soon as I started driving back home to Memphis TN (about 200 miles), I noticed that my voltage was low and the battery light was on. A quick check confirmed my theory that the alternator completely died. I shut off all accessories and hit the road, feeling pretty confident that I would make it home no problem. Then I hit heavy traffic and got concerned. After sitting through 30+ minutes of traffic, I wasn't feeling quite as confident. But once I got moving I made it home no problem. The only reason I made it back without problems is because I have a big Optima Yellowtop D34 battery in my trunk. If I was using the tiny group 51 battery that these older Honda's come with, it would have died well before I got back home.

Hmm you got me thinking about the voltage drop across the chassis since I am using it as a battery ground, so I did a bit of testing to get some numbers. I ran a a 2 gauge copper battery cable from my battery's negative terminal to one of the strut tower nuts in the trunk and I grounded the engine to the chassis with about five 4 gauge copper cables, making sure to sand all connections down to clean, shiny metal. I get about a 0.14 volt drop from the battery negative terminal to the engine block while cranking the engine with the fuel disabled, nothing to worry about in my opinion. I also tested the voltage drop across the 2 gauge copper cable that goes from the battery's positive terminal to the starter's positive and it loses about 0.36 volts while cranking, which I don't think is bad but I was surprised to see that a thick copper cable loses more voltage across the same distance than the steel that the chassis is made out of. A channel by the name of CE Auto Electric Supply tested chassis ground vs 15 feet of 1/0 copper cable and found that the chassis was actually a measurably better ground than the huge cable. So my suggestion is to use heavy gauge cables (ideally 0 gauge copper or heavier) and if you choose to run a negative cable from the battery negative to the engine, ground the battery to the chassis in the back also since from my testing as well as CE Auto's testing, the chassis drops significantly less voltage than even a 0 gauge copper cable. Just be sure to make proper connections to a clean, thick piece of metal with good nuts and bolts that can be torqued down tight, don't use self tapping screws. Electricity takes the path of least resistance, so you will never make anything worse by adding more paths for the electricity to flow through. Hope this helps!

What your missing (and what he explains) is that chassis grounds corrode and cause issues over time. I’ve experienced the issue myself with a rear mount chassis ground that initially worked great but then eventually caused a 3 volt drop on crank.
@averyalexander2303
@averyalexander2303 2 жыл бұрын
@@karenthomson9749 That's true, but broken or corroded chassis grounds will cause you problems regardless of whether the battery is grounded to the chassis or the engine, although most likely worse if the battery isn't directly grounded to the engine. Battery cables can corrode over time too, especially if they aren't soldered/crimped properly and sealed with water tight heat shrink tubing. I also like coating the bolt end of the ring terminals with copper anti seize, it helps prevent corrosion and keep the connections healthy.

Question: Have you ever seen issue with running the alternator cable past important wires? For example, I have an alternator wire tucked under my intake manifold and it passes near injector wires. Could it cause interference and poor function? What if it goes by coils or spark plug wires? The ECU? Thanks for all you do!

He says the bigger terminals go inline with the battery positive cable, but the illustration shows it on the negative side. Which one is the right answer?

When drag racing people who use the smallest battery possible are very often the ones who get driven around on the big end because their battery voltage has dropped from because there battery and electrical system cannot keep up with the demands of the starting the car and then the ignition system on a pass. Generally speaking since most cars like some ballast somewhere (over the drive axle or to compensate for the driver) means that you don’t actually pay any penalty for using a big lead acid battery or two with lots of reserve CCA. I normally like to run two batteries and have a plug for a jump box to start the car or run fans before the run and after the run before the car gets back to the pits where I isolate the two batteries and plug eat into a separate battery charger. The cars battery are wired in series that supplies the cars electrical system needs while making a pass and are isolated by pulling a shunt so that each battery can be charged with its own charger. Each battery and charger uses safe-t-connect connector to avoid mishaps in the pits and besides it keeps people from wanting to “borrow” your battery charger as much. I also use a small rechargeable battery from a cordless tool manufacturer as a backup battery to my data-logging system.

I'm really confused now because of the phrasing. Is this the go-to way to branch off only from the starter? So pos battery to starter, starter to alternator, starter to power distribution block? Can someone confirm this? I'm running all new wires and can't find one sure way to wire positive leads. I get the grounds part though.

Fantastic info thank you so much! Would you kindly comment on my style of starter circuits? My GM buddies hate it lol, but I always use a "Ford style" starter relay so I don't have constant power in the hot & cramped starter area. If the starter also has a relay then I send a trigger wire from the "I" terminal. I use a good quality heavy duty relay, Cole Hersee brand seems pretty good. I am curious your thoughts about this and also about using diodes or resistors to prevent fly back. Perhaps the better relays don't need? Can't find a solid consensus on the web.
