97 SkiDoo Formula 583 Volt Reg Replacement with Kimpex
I've been having issues on my 97 Formula 583 in that the rear tail light is always on and brake light on dash when started and idling ... when I rev it up the tail light blows as does the low beam. I believe it to be the voltage regulator and replaced it with a Kimpex 01-154-15 but problem persists. The 2 wires off the Kimpex are one is black the other yellow whereas the original ski-doo on was YL and YL/BK. I couldn't find any instructions on how to wire up so thought it to be BL to YL/BL and YL to YL... does that sound correct? I'm gonna measure the AC out tonight but if not the regulator what else could be my problem?
Do the other lights blow? If not, the problem lies in the taillight/brakelight circuit.

According to Kimpex, that is the correct regulator. My concern is that there is only 2 wires. typically Kimpex have two yellow and a black. Ones that charge battery may have a green/yellow.
Black is usually grounded to the frame. In fact, if you do a continuity test between the black and the case, it will zero ohms, dead short. The black wire is in case you cannot mount it to a bare metal part of the frame.
Cleaned up some wiring that had frayed... Put back original regulator and tested.. Stays at 12 .. 13 volts but brake light stays on.. Electrical brake cable is loose and comes off easy at brake lever ... Keeping at it
I read in another forum that people who wired this regulator found there was a feed back through the ground that keeps the indicators lights on. One guy put a diode in there and solved his issue, but I'm just not confident with it.
I suppose it just depends on how the stator is wired. If it a 2 phase stator, then ground is a common (like the white wire in house 240 Volt circuit). My understanding is most are not and they actually have two separate coil windings and that the ignition circuit uses engine/frame ground and accessory does not use a ground, but rather much like a house 240 volt, it has two "hots".
yesterday after cleaning up the frayed wiring and I put back the original Ski-Doo regulator and measured the AC it stayed around 12v even after reving but problem persisted ... I took a closer look at the Hydraulic brake power cable referred to as a microswitch and the cable was loose and appears broke off in the brake lever so this maybe my problem all along... will look to buy a replacement
I replaced the microswitch as it had snapped off... brake light now works as it should and I'm not blowing bulbs... not sure if that fixed it or when I went thru and cleaned up some wiring that had the insulation burnt off it... so that has been fixed but now got more problems... I guess that's what ya get for getting an older used sled
