I dont have a circuit board to verify if it's there or not and if it isn't thanks for the correction.


72step, The brown wire which went to the alt. light is to excite the alternator and has no direct effect on the ammeter. Earlier I stated that "Delco recomends on models with a gen light that the reisistor wire be installed parallel to the gen light circuit but I don't think GM did this" and you indicated that there is a brown/white wire tied into the brown wire. If thats the case you should be good to go, I cant verify this but you can by checking the brown wire at the voltage regulator for power with the key on only also note the voltage drop to verfiy resistance. Delco recomended this to add redundancy to the chargeing system, if the alt. light ever burned out your charging system would still work not leaving you stranded.

Pole question, Mine works.

I'm quoting your whole post because you are right in both parts. I have a seven gauge dash that shows the lead from terminal 5 going to the second light from the left which is indeed the temperature light on the three gauge dash. I should have clarified my statement that terminal 5 goes nowhere to read that it goes to the old temperature light but that is not used on the seven gauge dash so the circuit board strip goes there and stops instead of just saying that it doesn't go anywhere. terminal 5 is a ground side terminal on the light so unless it's grounded then the light is useless. I found a dash to illustrate this as you can see the terminal 5 strip to the second light from the left. I can't understand why the conversion isn't working if the pins on the connector are changed and the ammeter wires are added as shown. This conversion has been done dozens of times with good results.
