hey folks, in the process of installing a GM alt into my 94 22re. ive got it pretty much done, however one wiring issue has me a little stumped. in one swap, posted here: http://www.rocketcityrockcrawlers.c...ner%20alternator%20Upgrade%20Project.pdf
the two wires are listed as being #1 as the field wire and #2 as the regulator wire. on my alternator(not the powermaster, its out of an older chevy truck, it was free, took it to autozone and had em test it, it works) it has 1 and 2 stamped into the housing on the back of the alt, however it has a small 'r' and 'f' stamped as well, but they are the opposite as listed for the powermaster. anyone know of any way i can be sure which is which? and if i wire them up backwards, will i do any damage to my electrical system or ECU? im thinkin i should go by the stampings on the alt. that i have. any input appreciated
