1992 907 ie Charging System: a backstory and a question
Posted: Thu Mar 07, 2024 6:11 pm
Hey guys,
I picked up a 1992 907 ie w/19K miles last fall and have spent some time over the winter performing the usual maintenance items in order to have a baseline. Have refreshed all fluids including fork oil, changed the drive belts, and have checked brake pads, wheel bearings, etc. I did note that the bike appears to be running off the battery, am reading 12.7v across the battery while running with no change while rev’ing. I had originally planned on installing a new reg/rectifier this spring, but noted in the PO's maintenance records it has been replaced twice so far. One was a RR from Rick’s in 2013, the records show another was replaced, but with no date or manufacturer. The RR in the bike looks like a Rick’s.
So I’ve done some reading and think before I toss more parts at the bike it would be prudent to check the AC output at the yellow wires, check continuity of RR wiring to their terminations, polish all the grounds I can find, etc. Have done a great deal of reading here, very helpful for sure.
I won’t be able to check AC output until the weather breaks, we seemed to have our January thaw in February and now it’s spring. About a month early. I live on a dirt road and it’s atrocious, so I won’t be able to get the bike out for further testing for awhile.
So onto my question. On the wiring diagram I noted there is a 30a fuse on the red wire, between the RR output and battery. It also feeds the fusebox, but after tracing the wire as best I can I can’t locate it. Any clues as to it’s location? I'd like to pull and check the fuse, polish the blades, and then check wiring continuity.
Thanks,
