mallory rev limit tach restoration

[musclcar]

okay got the tach all purdy'd up ,i re painted the bezel with chrome paint and fixed the gauge cup with fiberglass bondo and sanded it smooth.so now the tach looks really nice now the @#$$%thing will not work right.it first acted like it was on the wrong cylinder selection because it read high. i readjusted it back to reading an 8 cylinder and the rev limiter works fine but the shift light and face plate light doesn't work.the shift light was working when i first hooked it up but now it doesn't,i hope it's bad bulbs.

does anyone know of a place that refurbishes electrical items like this mallory rev-limiter tach ??
