There is also the MAD Electrical modification for safety, IF your car is a driver, not a original OE factory vehicle.

Just had an over charging issue with my 70 Charger last weekend of some sort I think. I have been chasing a missing issue. I thought it was within the carbs. I was holding the RPM's at around 3500ish to listen for the miss & then all of the sudden my Amp gauge pegged, my after market Autometer monster tach pegged at 9500 (even though still at 3500), wipers turned on one time all by them selves, radio was off but a turbo whistling sound came thru my speakers, my driver side door was open & all of my interior light bulbs blew out but the fuse is still good. I shut it off as soon as all of this happened & tried to start back up & now everything is dead. I disconnected the battery & the Tach is still stuck on 9500+ RPM's even wth no power. Haven't touched it since so I am not sure what happened yet. 1963 Belvedere 440 Max Wedge Tribute 1970 Charger R/T S.E. 440 Six Pack 1970 Challenger R/T, 528 Hemi 1970 Charger 500 S.E. 440 4 BBL 1970 Plymouth Road Runner 383 1974 Chrysler New Yorker 440 1996 2500 RAM 488 V-10 4X4 2004 3500 Dually Cummins 4x4 2012 Challenger R/T Classic.

I'd suspect the regulator 1st and check the green field wire for a short live every 24 hour block of time like it's your last day on earth

Just discourage, so I had to walk away from it for a little while. 1963 Belvedere 440 Max Wedge Tribute 1970 Charger R/T S.E. 440 Six Pack 1970 Challenger R/T, 528 Hemi 1970 Charger 500 S.E. 440 4 BBL 1970 Plymouth Road Runner 383 1974 Chrysler New Yorker 440 1996 2500 RAM 488 V-10 4X4 2004 3500 Dually Cummins 4x4 2012 Challenger R/T Classic.

The factory wiring and amp gauge is not rated for that much currnet , one would have to make some major wiring changes to do that . What the OP is seeing is NORMAL .
