i have took the alt out and had it checked twice and had the batt checked and come up good all around. All thee studs on the alt have the same voltage as the batt but i was also told that that the back of the alt should magntise when the alt is on but it is not.


any help would be great

o it is on a 91 intercooled 12 valve

 

use the search button. it is a very common problem. first off, check your external regulators. the charge goes through those, regulate the voltage, sends it through the computer, and then the computer sends it to the batteries

 

where is the voltage regulator and where are the 3 relays that i have read about on my 91

 

i believe the voltage regulator is in the center of the firewall above the engine but i could be wrong. i dont know about the 3 relays though mine is newer than that

 

check this thread out also ironworker and see if it will help too https://www.dieselbombers.com/1st-ge...lternator.html and what part of missouri ya from

 

about a hour east of Kansas City. I can not find the voltage regulator i have looked in the center of the fire wall and under the dash with no luck

 

there is a 100 amp fuse in the fuse box or right next to it

 

i look like a dumb it was right there in front of my face put a new voltage reglator and it fixed my prob thanks ever body

 

great awesome thanks for the update
