I have power to the left side of the fuse panel but if I turn the light switch on or turn the key to the on position or step on the brakes the power to the fuse panel goes off. Any ideas? Thanks
The right side of the fuse block is fed from a red wire that originates at the starter and terminated at the place the battery cable is. I would check that connection at the starter and the battery terminal and the NEG terminal to frame. If that all checks OK then take a look at the horn relay junction block for good connection
I’m sorry it’s a 1968 checked connections seem ok I have power from the horn relay to the fuse panel but if I pull the light switch on I lose power to the fuse panel even if I turn the key on to run it loses power to the panel.

Check the heavy gauge red wire connection on the back of the fuse block. And just to clarify, when you turn on headlights or ignition, does the voltage on the fuse block drop to zero or is there still some voltage present? Like 2 or 3 volts maybe?
I ran a wire from the battery to the horn relay hot wire and pulled the light switch out and the lights turned on so I’m thinking something with the starter connections and going to check that out.

If totally blown open I do not think so...but if burnt up maybe. Could also be a loose bolt or broken lug on the main battery terminal at the starter solenoid bolt assembly where the battery + and horn relay wire come together.
Electrical problem
