I have a '74 FJ40 with an F engine Manufactured in 12/74.
I am having some electrical related issues and need some help.
This all started because of on off idle hesitation. I replaced the Cap, Rotor, Spark Plug Wires and Spark Plugs and set the timing.
Now when the engine is first started it runs fairly smooth, but when it warms up it starts missing real bad and blows the 15Amp Turn Fuse.
While trying to diagnose the problem I have also replaced the distributor since the shaft was loose and causing erratic timing, also the Ignition Coil was replaced because I thought this could be causing the problem due to heat.
I have double checked the wiring for the Ignition Coil - Black Yellow wire is going to the Ballast Resistor, Black White wire from starter selonoid is going to + on Ignition Coil, Black wire from Distributor is going to - on Ignition Coil.
While looking at the wiring diagram I can see that the wire off of the 15Amp Turn Fuse also goes to the Voltage Regulator and the Hazzard switch.
I am at the end of my techical abilities and need some assistance to get my FJ40 running again.
Sorry if this is too long or not completely clear, but I am frazzeled.....
