I have 1988 camaro i-roc it had a v-6 in in it some one change it over to 350 can,t get it to charge can you help think sam

The alternator wiring is the same for both engines.make sure you have power on the large red wire at the alternator and the plug connector is clean and tight for the 2 wire plug for the regulator.it should have a small wire from the battery wire to this 2 wire plug and the brown wire is generally used to put out the light on the dash when its charging.next there is a D shaped hole on the back of the alternator that you can insert a metal cotter pin into until you feel a tab and ground the tab with the cotter pin by touching the pin to the alternator case and the charging system should start to charge.use a volt meter to check the voltage.if it doesn`t charge when you do this or you don`t hear the charging system start to charge then the voltage regulator is not working and needs replacing.
