Hi All
Im lost
going to wire the barrery to the starter and then the alternator but do not know what wires go where I THINK I run a LARGE cable to the starter and then run a cable from the starter to the alternator but if someone could tell me step by step that would be great I have a 2lt pinto engine with a lucas alternator

Large wire from battery positive to solenoid terminal on starter motor.

Smaller cable from same terminal on starter to alternator output (4mm if the alt is a 40amp one) this is for charging battery.

Cable feeding loom through a 40 amp fuse to same terminal on alternator or on battery positive.

Same as me. it really could not be easier.....
large wire from bat to starter (pre-engage type)
Thick but no where as big (50A capacity) from same connection on starter to EITHER large terminal on alternator. the small connection connects to ign. bulb on dash and it to your ign. sw.
i have in various places on this forum an article on wiring your car, read it. Perhaps the site admin can pin it for easy reference.
if something as simple as this has caused you problems i strongly advise you to get your cars electrics checked over by some one competent. before your car goes on the road.
