The GS Diary Day 63: Another gift from the PO.

Once again I'm scratching my head trying to figure out what the hell the PO was thinking (or smoking)

What started this was the box sitting where the voltage regulator belongs. It's a CDI from a 1980 GS850 and it's wired into the bike somehow.. going over the wiring diagram shows the coil outputs are hooked up to ?? The wires run off into a ball of tape.. the pickup lead is just taped off and left hanging.. I can't see how the hell this thing is doing anything.
Voltage regulator is MIA.. a mystery to be solved.

With the GS wiring diagram in hand I started tracing the mess of wiring, electrical tape and garbage to see what the hell was going on..

First thing is to check the ignition.. a CDI must be tied into that somehow right? umm no.. points and coils are still wired up stock..
Good to know.. moving on..

I started from the CDI and worked my way into the mess.. Only 2 wires are hooked to the bikes wiring harness.. both are the coil outputs from the CDI.. Following those through a bunch of patches I get to a pair of wires spliced into the main harness.. These are Yellow and white/green wires.. Eh? those go to the stator..

Tracing the wires confirms it.. the stupid CDI is plugged into the stator where the voltage regulator goes.. Whoever did it even took the time to make up a little wiring harness to make it a plug in install.. Lucky thing for me it's easy to unplug & chuck in the parts bin.

I thought I'd get all smart and use the regulator from the GS750.. That's not going to work either .. It's a single wire regulator.. the GS1000 unit controls 2 fields on the stator..

Not wanting to throw good money at a old unknown regulator to go with the unknown rectifier I chose to upgrade the whole thing.

I ordered up a FH008 FET style R/R from a 07-09 CBR600RR.. Should be here in a few days..

Other than that I picked up some aluminum plate and bar stock I needed to get the rear sets mounted..

Carbs are mounted.. another mess.. I thought I'd use the GS 750 throttle cables as the GS1000 set was broken.. Well as it happens the GS750 uses a different handle bar housing that the cables don't fit so I had to swap the housings out till the new cables arrive..

I'm now 3 weeks behind my original schedule to have it running..

Good news is The Dyna S ignition is here and new GXL wire is in with the correct tracer colors to repair the wiring harness.
