If you're gooing to ugrade the alternator by all means upgrade the size of
wire from the alternator to the battery. This may cause a problem going
through the Ampmeter though. You may want to consider changing over to a
shunt style meter. Now for the question I can't answer, can you find a
meter that will fit in the alloted space.

Bob Thanks!
I have the 48 amp Lucas,which isn't enough. I'd like to know the model
or part # for the Delco you bought. My Stereo draws @25 amps, I guess head
lights to be @ 12 amps, wipers ?, heater fan?, ignition maybe 10 amps? new
radiator fan @ 12 amps. mmm on second thought maybe I should get more than
65 amps. Any idea of wiper motor and heater fan load? Oh yea, did you
upgrade the wire size from the alternator to the battery?
Thanks Nick
