glow plug non mb question
 

hi,

i need help to find a 12v glow plug substitute for the 5v plugs
in my 1981 isuzu 4x4 diesel pick-up.
the only plug i have been able to find is a bosch 5v #80016.

the isuzu glow plug system is complicated with two relays, a dropping
resister and a "glow plug controler". the system failed somewhere, so i
jumpered from the battery to the glow plug bus (series system) several
times and then rewired with a ford 12v relay and push switch (to take care
of the problem for good :rolleyes:

found out the plugs were 5v and they were fried :dead: . so to keep it simple and not have to wire in a dropping resister i need 12v plugs. where are they?

don

Sorry.
 

The ISUZU diesel was never crossed to a 12V glow plug system.
I searched for after market conversions with no luck.
You should restore the OEM system, or make a new custom circuit for OEM glow plugs.
