09 bird 4 wire regulator wiring question

wjack57 · 12-10-2009, 12:08 AM

I bought the used bird with the headlight circuit bulbs burned out and it wasnt charging the battery. When checking the wiring, I saw that one of the regulator tines was broke off. I replaced bulbs and ordered a new regulator. When I installed it, I started the bike, reved it up and immediately blew out the bulbs. The battery still doesnt charge. When checking for voltage at the regulator, I get all kinds of funky voltage (like a/c where it doesnt belong), I suspicion theat the kid I bought it from rearranged the wires in the connector.
The wire arrangement as found (looking at the female side of the connector, with the latch up) is top left :yellow ; top right is: red ; bottom left: green ; bottom right: yellow ( turns to pink at the stator connector).
The male side of the connector is integrated into the regulator itself.
Any help is greatly appreciated, Im pretty reluctant to just start to arbitrarily move wires around.

it sounds like your stator or rectifier might be toast.

my '82 GS650 had the nearly the same issues, as well as our '87 LT250R.
the rectifier was out on the 250 (voltage all over the spectrum A/C), and the stator was not grounded correctly on the 650 (killed the battery).

check all your grounds and scrape any painted grounding surfaces.
good luck and let us know if you find the problem. I cant help with the wires...

I bought parts from electrosprt.com, very fast with info and parts, and they have a great diagnostic section online

I went thru the wiring and found the ground wire to have about 1 strand connecting it to the ground circuit, I gave it a dedicated ground. I found the yellow wire for lights to be all but broken at the rectifier spade terminal, I cut back the wire and put on a new spade. I found the red battery wire to be in pretty bad shape, so I replaced that terminal spade also. I fired it up and get 12.2 vac at the headlanp socket. I also am charging at 16 - 17 vdc. Too much I guess the reg is malfunctioning or it had the wrong one to start with and I replaced it with the same.

Thanks for the help so far- Jack

It's not the stator. If that was the case you'd have not surged the voltage and blown the bulbs. It's the regulator/rectifier, which BTW, was a common electrical failure point on many older Japaneese bikes.

Where the R/R is on your bike, or how to test it I don't tknow, but I bet that's where the problem is.

what Doc said on the rectifier ...

I get long winded after a few hops and barley :wink:

Hi, The ac voltage surge was caused by the bad wire/connection at the regulator, no place for excess voltage to go. Ive got a new regulator on order. At least the mounts on it look like they match up to the bike mounts and the connector looks right. Ill know in a few days.
BTW, a Ford solenoid works just fine on my bird. Just had to change the mount. -- Jack
