Engine/Transmission (1994 - 1998) a grid heater question and a fuel heater question...

[Will24]

Stupid question time...



Are the grid heater and the fuel heater both straight 12 Volt DC circuits? I want to wire up two LEDs as status lights for both of them in my cab, but I can't tell lookin at my FSM if they are both 12 volt.





Thanks Guys!

Grids work from solenoids, and a temp sensor. Not sure of the fuel heater though.

What was said on the grid heaters, the fuel heater is also 12V, is only on below 40 and off at 60 (F). Thermostat is inside fue heater.

Will, FYI, in case you don't know. The relays for the two grid heaters do not always come on. They work independently so you may want to attach a LED to each one. The hot side of the relays is always on when the key is on. The PCM provides the grounds when certain parameters are met.
