Ballast resister

Ok, Ive checked all the pos wires in the engine compartment with a circut checker and every thing has power going to it. So the problem is under the dash or ballast reister. What does it look like when it is blown? The coil looks ok but the porcelin that it is wraped around is cracked.

I would replace the coil first and then see where your at. Jim

It's usually burnt on the back side

Ive changed the ignition switch also. On the back side of is marked GRD, ACC, ST,IGN2,IGN1, Should the BAT have power running through it? Also the red & black wires coming from the 4way junction on the inside firewall do have power going through them. Ive changed the starter relay, ignition switch, ballist resistor and used a circuit tester. What else is there?

2morrow is the last nice day b4 winter. Id like to get this done as I dont have a garage. It looks as though both the red and black wire at the firewall junction, travel to the volt gauge and the power gets distributed from there. That metal bar that joins the volt & fuel gauge, is it pos or neg? The next place to distribute power would be the ignition switch.

Do you have electronic ignition? if so then it may be the magnetic pickup in the distributor

Fuel gauge is feed from the bus-bar that is attached to both fuel and volt gauge. The power should then exit out the black wire on the fuel gauge right?

red wire feeds the busbar from key by way of splice near or at wiper switch, black to fuel sender, blue
is feed to temp gauge

does someone know what the resistance is of the ballast-resistor? my builtyear of the crewcab is 1969....
