FLH positive battery wire gauge

#1

Post by flatheadDave »

I’m redoing the battery cable and the starter solenoid cables on my FLh. What are the min gauges? I have a 6 gauge positive wire for the battery to solenoid. Will that be ok ? Or do I need 4 gauge ?

I always try to use #4 welding cable, but for a true restoration you may want something else.....

6ga. seems to be the size on my shovel. IMHO, you should use stranded cable with a PVC outer sheath. This may not be the "correct" cable for a restoration, but this is NOT the cable to swap around for a better "Look"-- it most definitely will put you walking (looking now at my cables, it seems to be high twist-rate copper stranded cable --good engineering practice, I think.) This cable touches hot motor components and rests against the steel frame. A more heat-tolerant insulation material would seem appropiate.
Hope this helps,
Good Luck,
Joe
