Bought a 37 ford couple months ago. Its got a chev 350 and a chrome alternator. On the top where the stock plug would be is a red cap and on it it says romove to change amps. On each of the four sides of this square plug it says HI LO "2" "3". Ive never seen on like this before. which way do you face the HI to get the high amps etc.
Thanks andy
