1. I just purchased a 140 amp powermaster alternator. It says to upgrade the charge wire to at least a 8 gauge? Is this the wire that connects to the stud on the back of the alt. and does it go from there straight to the battery. Mine seems to disappear in a wire harness going back towards the firewall? Some insight on this would be appreciated

2. Will a tach out of a v-6 car work in a v-8 car? I know the oil sending unit is different btw the 2 (60 psi -v-8 80 psi v-6) I have been looking for one to replace mine at the local yards and all i have found is v-6. If it will work i need to replace the oil sending unit anyways.

 

I got a tach from a v6 car and it works (the needle moves), but it's not accurate.

 

It is not neccessary to replace the wire since normal charging current is way below 140 amps. Typical output from a 140 will be between 35-50 amps normal driving. The chip in the tach has different jumpers for 6 vs 8 cyl engines. I'll try to pull the data and post how to change it.

 

Thanks for the reply. I guess I can quit worrying about my wiring then. That alternator is fantastic. I dont have any problems now with the help of the cvr mini starter,optima red top batt.,powermaster 140 amp alt., and remote solenoid(which i pobably dont need any more)
