alternator

[HobbyMan]

If you have read my other forum, my dad got a new XS. 79SF. It came with extra parts. Among those parts is an alternator complete with the 2 coils. THey test good ohm wise, but the wiring is bad. It is intermittant at best. Does anyone have any suggestions as to replacing it? What guage do I need and Should I just shrink-wrap it?

[HobbyMan]

any replies?

Hey Hobby,

I think the problem is your terminology. The Alternator and Stator has coils of wires wound in them, as well as wires that run from the units into plugs! You just said "WIRING" was bad?? If you mean, just the external running wires and plugs, then replacing them would probably be good to do, again, as you said, the coils ohmed out correctly and didn't show any shorts/breaks!

Sorry about the confusion. I am reffering to the coils as their own entity and the wires are the external wiring. Yes the coils themselves are ok. its the external wiring from each of them which is intermittant. When I move the external wires around, I loose continuity. I just need to cut off the external wiring on each of the coils and solder on a new section with the connectors at the end. On the outer coil (alternator I think), I don't know where to cut the insulation and the wires. I know the closer to the actual coil is better, but there is some twine looking material wrapped around the wires. Should I cut the twine and solder new wire where it actuall joins the coil itself, or should I leave a section of the old external wiring and splice on a new section? I think I can figure out where to splice new wire on to the inner coil (stator I believe), but I don't know what wire would be best to use for either wiring extension. I have plenty of wire which I believe would work, but the original wires seem to have a cloth insulation, in stead of the normal rubber insulation. Would this make a differnence?

Perhaps DiverRay or Geezer or Randy,
All much more experienced with electrics than I, can reply about the wire type, and purpose for the cloth insulation!!

I would think due to the location of the wires running along the engine and near the pipes, that the cloth/fiber insulation provides a better thermal protective layer than just the plastic, along with perhaps also friction/rubbing resistance as well!?!?

Thanks for the help.

Alt-ternative wiring?

Think it's only 16 GA.
!4 GA would not hurt.
Fewer connections/splices are better. Some resistance in each plug/connector or soider connection. Cloth/fiber insulation does not melt, but wires from alt to plug behind fuse box are "wrapped" in a plastic sheath. Think there are four wire holders to keep wires from exhaust and neatly tucked up against engine.

I think 16 gage is a but larger than stock but would be just fine. I have the plugs on my website.

I have the plugs, but where can I get the cloth insulated wire?

[Geezer]

Not required. Regular insulated wire is just fine.

Cool. The only reason I wondered was because of the heat from the engine and exhaust and the fact that the original wire has the cloth type insulation. Thanks for the info.

[Geezer]

The wires go through a rubber plug and shouldn't touch the exhaust. It wouldn't hurt to put heat shrink tube over the wires but it isn't required.
