Alternator gauge is smoking

Hey all, I just installed a new gauge cluster in my 1972 duster and when the car is running smoke comes from the alternator gauge pegs. I’m not sure why this would be, I’m wondering if anyone had a similar issue or knows the fix? Thanks
Some Mopars owners choose to bypass the ammeter altogether and/or replace it with a volt meter. Apparently there have been a number of cars burnt because of such issues.
Good luck
