faulty motorcycle rectifier/regulator, diagnose and replace

[@craigleeofficial]

Ive been swapping out pilot jets. Setting and reseting valves. Spark plugs in and out. Coils changed etc. On my '90 535. Front cylinder keeps cold and neat fuel comes from the exhaust. It backfires and pops just like this. Today I tested the rectifier regulator as a desperate resort. And, from my understanding of the readings, it is faulty. New one ordered. Let's hope it solves my issue!

Hopefully, with mine, it was above a certain RPM that the motor would misfire and run badly... In the last couple of weeks it developed a starter issue, old bikes ;-)

You do such a great job explaining basic maintenance on your bikes. Great job, as always. Eric

Rectified the rectifier, good work, Nic. No excuses, off to work. How ya doing, mste? Ride well. Cheers

All good, I love my job, my boss is great, my coworkers are champions, and I'm well aligned with the organisations goals and vision I'm looking for a triumph speed twin 1200, rare in these parts of the woods...

Great job mate, 👍

High installation resistance from regulator plus to battery plus or regulator minus to battery minus can destroy the regulator. The first sign is that the battery voltage in operation is lower than 14V.

[@aussiewantok]

mine is at like 13.1V atm...

[@3FHVSP]

@@aussiewantok, If it is the voltage at 3000 rpm, check the voltage on the plus and minus connectors from the regulator/rectifier. There should be 14.3 to 14.5VDC at 3000rpm. And if it's OK, check where you're losing voltage. At least 13.9V must be achieved on the battery at 3000 rpm.

Seems to be one of the most common electrical faults in bikes.

[@Nicontrast]

Ah the regulator/rectifier. I am well versed with what that does. Hope it keeps doing whatever the hell it does.

[@aussiewantok]

I have a little meter on the bike to tell me the regulator is doing that thing

[@marscobras8281]

Hey Mr. With my bikes I want to see 13.5 to 14.5 volts. 12.6 is just a standing battery, not charging...when you see 11.5 you know it's going dim

[@aussiewantok]

@@marscobras8281 I agree, but...the volts on display on the meter are taken off the light circuit. It's wired up to work when the lights are on...

[@hachewie]

And it’s rectified.

[@user-bo5ho7wl4w]

hello, isn't it supposed to give at least 14v?

[@aussiewantok]

@@user-bo5ho7wl4w mine generates 13+ constantly, runs well

[@RobertMiller-hw9ql]

Would the rectifier cause the battery yo smoke when try ING yo start it

[@aussiewantok]

@@RobertMiller-hw9ql I recon it is possible, unwieldy current running through the circuit

[@hachewie]

Hahahaha. Work. 😢😢😢

20 hours before I start...work...
