still working on electric almost done.my oil guage is pegged do you think its a bad sender if I disco it sender still stays pegged I took guage out and goes back to zero and 1 of my blinker dash lights stay on but everything works fine any ideas???

If one of your blinker lights stays on that could mean you have a bad bulb turn the one that stays on say its the left turn the switch to blink the left one and check the bulbs front and back if one inst blinkin thats prolly why my trucks blinker inidicators light up constanly when one of the bulbs is bad


I had a bad sender on my engine awhile back that kept the oil pressure pegged .. When the engine is not runnin is it still pegged ?

The sender wire might be pinched somewhere and being grounded.

you've got a bad ground somewhere if the turn signal bulb is constantly on.
