Oil pressure switch choke wiring

I have rewired my engine compartment. I used the diagram below for the choke, manifold heater etc. The only thing I did different was use cx in the bulkhead instead of cz. Not sure why I did it has been a couple of years since the rewire and I'm just now getting around to starting it. It keeps blowing the 15 amp ign lps fuse which goes to the dash gauges. When I unplug the oil pressure switch the fuse doesn't blow. Is it too much for that fuse? Do I need to put it on cz with the back up lamps or do I have something else wired wrong? Thanks any help is appreciated.

Yes, The manifold heater draws too much current for that fuse.

It might be enough to power the relay and the electric choke but best to run choke and relay power to CZ.

The power for the manifold heater (30) should come directly from the battery directly from the fusable link. Not from anything coming out of the bulkhead connector.



There is a pale yellow trace on the above drawing that shows were the power for the heater actually comes from.

Thank you. I didn't realize the heater went to the battery. I have rewired this Jeep from scratch and learned everything form this forum. Most of it came from You and Jeephammer. I cant thank you guys enough.
I just came across what i think is one of your diagrams (below). Just to clarify should i be wiring it like this? Do i run it straight to the solenoid with a fusible link? Most all of the factory wiring is gone and was severely hacked up by the po.

That would be the best.
I think the factory used one fusable link for all the electrics but you could just add one and attach it to the terminal post on the star solenoid were the battery cable goes.
