restoring a 57 88 coupe
having trouble with wiring, I have a new harness from Fusick,the circuit board seems ok all lights work except the HOT light when you turn the key on, sending unit is new and checks out
also both signal indicator lights flash,at the same time regarless of the position of the switch, remove one blub turn off the ignition put the bulb back in and they work properly try it again 5 minutes later and they both flash, both front and back signals work properly all the time

anybody got any ideas
