Hoping to get her running today! Going no fuse. Made sure the cables I got were all 4 gauge cable. I will upload one more before hookig up the battery
You don't need a ground cable on alternator period... It's grounded when bolted to block... Unintended shorts(grounds) are what blows fuses, no reason to ground a fuse, EVER... In the event of overload or short the fuse is sacrificed to protect wiring...
Just to clarify some terms/ clarify thinking. there is no ground is DC electrical. thinking of it that way clouds ones mind when troubleshooting. there is only positive and negative, in DC wiring (ok to be really nerdy if you want to talk about a point of zero potential inside the battery) "Ground" refers to AC wiring where there is positive neutral and ground Ground (in AC wiring) is a non current carrying conductor under normal conditions (wire) and in an emergency to carry the positive wire current away and to earth ground in the event that the pos wire chafes through and touches the case of the tool / toaster whatever. Think of DC negative as being equally important, (because it is) 12 volts DC goes around in a circle from the, to the device then travels back to the battery and wire size for the DC Negative is to be equal in size to the positive wire. on an alternator, lets say were running 4 gauge positive to the battery. 4 gauge negative to the battery is appropriate, then, as well. I dont like to count on all the iffy and slightly rusty connections, on the alternators negative path to the battery, the bracket, acrross the block, over to the body, etc there are many points of failure, for the voltage to degrade. Run a heavy wire from the alternator case to the battery negative and all future toubleshooting becomes simplified. I also run a negative battery cable straight to the mounting bolt of the starter motor to ensure good current is getting to the starter motor.
the black wire on the solenoid is the pos output of the alternator, correct? then I think you are good. on the alternator, try to not have the pos wire insulation rubbing on the hex nut. itll rub through in time and make a short /fire
Ummm not what I learned almost 60 years ago, at that time home AC wiring had no ground and chassis, engine block were ground... Includes the old 6v systems that positive was connected to chassis, those were referred to as positive ground... As long as battery cables that carry current are sufficient to operate starter, a ground(ahem, negative cable) on alternator or starter to battery is totally useless... No it can't hurt but not necessary... Bought my first car 51+ years ago, yet to need either...
