Dead electrics 88
-
Looks like the loom on my red 88 is not the original therefore I don't have a spare, have new one (3db) that will be fine for the next rebuild, suspect loom was changed at same time as engine change in 1991(3rn). Will have to repair the one on the bike now, joy!
@oldman I'd have to look at the diagram, but there is only going to be a few cables that will cause this type of fault. So with it stripped off the bike, it shouldn't be too hard to find.
But I don't know if doing it whilst on the bike would make it easier.
My experience tells me that it'll be one of the wires from the ignition barrel to the loom. Since this is located around the headstock, they often get twisted and crunched over the years, it's the most likely to go wrong.
Furthermore, the battery cables tend to be thicker and less prone to failure.
I can't imagine it being the CDI, since the lights and what not are not controlled by the CDI to my knowledge.

Appears to be where loom threads through frame near ignition coil, going to strip later and see what I find

Stripped loom back from rear of bike and removed loom tape, bit of a mess really but damaged cable(black) only visual fault, goes to power valve. Cannot see that killing power. Going to remove completely and test for resistance and clean up what you see. A longer job than I thought but there you go, at least it's still winter!

That's the problem with a bike near on 30 years old. Guess when engine changed in 1991 loom was changed to suit, would originally been 3bn now 3rm. Was expecting to see limited damage and a relatively easy repair, as if!! Going to set aside some time to sort properly, probably weekend now, busy week ahead.

Wire corroded back under insulation , had to cut back about 25mm both ways, stripped loom tape back and found another poor join. Just testing loom through now, badly cut about, and poorly repaired before. Glad it came to light now tbh, would hate to be doing this in the warmer months, had an unexpected cancellation today hence able to repair now.

It was a lucky guess Calum, three wires in that joint, one to regulator rectifier and other to ignition. Could be what caused my reg/rec to fail last year. Thankfully seems to be fine after testing, could have been a disaster thinking about it. Just got to refit and put back together, thanks for advice. To be honest could not tell loom had been opened before or would have had a look last year when I was cleaning the loom up. Should not have to worry about it now.
