Im puttering around with the 1974 Honda XL 350...and the coil puts out a weak spark...It may have something to do with the fact the lead wire to the plug is only held on with the internal wire..the insulation is broken around where its molded into the coil itself. I suppose I could repair that with JB weld. The condenser is also molded as part of the coil, and it may be bad, so I picked up a used condenser from a bike yard and will splice it in.
I picked up a used generic 6vt coil for $10, and machined a mount to adapt it to the bike. I tested the coil by grounding the hot lead by scratching it to the frame and after 10 or 15 sparks, the coil split around the circumference . It doesnt spark anymore...shrug. It had no condenser attached to it. It "bumped" pretty good each time I sparked it. Had a nice brite spark too.
Im testing the electrical with a 6vt battery charger hooked into place of the battery
The wiring diagram I have and all references say that the Honda uses an AC coil, fed by an ignition winding on the alternator. Honda wants $80 for a replacement coil, JC Whitney sells an aftermarket "can" coil for $21, but doesnt indicate if its AC or DC.
Whats the difference between an AC and a DC coil????
Anyone got a surplus manual for a 1974-75 Honda XL 350?
