Baffled

I have accessory power to my gauges and fan, and the engine cranks, but I have no power at the fuse block (no juice to headlight switch, horn, brake lights, etc.). Help!

Are your gauges aftermarket?

Make, model, year would be helpful also any electrical mods beyond gauges?

Not all vehicles are wired the same way, hence the question.

I am thinking your gauges and fans are ran seperate from the factory harness.

Most setups run battery, starter, fuse block, switches.

Everything is ran through the key in most rides. The exception is the headlight switch. If the key was bad you would still have headlights. The only reason you would not have headlights is if you lost your chassis ground.

The thing would still crank because the block is grounded. But most of your factory items would be without a sufficient ground and there for no way to get power.

Throwing out options here. But check that block to firewall/chassis ground.





The more you can provide about the ride and the electrical system the better.

If you have an amperage gauge in the package and it goes open, that can cause your problem too.
