Not Charging after Madd bypass.

yes just be careful not to connect up the old wire again.... if the short isn't visible in the run in the engine bay it going to be at the bulkhead or under the dash

main protagonist when it comes to shorts under the dash would be an ammeter

they are held into the metal dash pod by their contact/ studs, which are insulated with plastic top hat washers through hole and fibre washers either side..... if those washers ware or melt alternator current flows direct to earth and you melt the main feed wire and potentially the bulkhead connector...and ...even worse stuff near by..

ammeter in this state can be fixed.. you just need to re insulate where the 2 fat studs pass through the guage caseing and do the inner and outer half height brass nuts up nice and tight.
