recently had a 74 javelin passed down to me. I have a fair amount of experience with a variety of cars, but not this one yet. Issue is the car is electrically dead. Every once in a while it will actuqally turn over with key, but most of time there is nothing. No lights, no solenoid click, nothing when you turn key. Has new battery and starter solenoid, Ground and positive cables fine. It seems like something related to ignition switch, circuit or???? Any suggestions? Finally found the accessory fuse board, but unsure what else to look for. Any assistance or suggestions will help.

Have someone wiggle the wires on the bulkhead connection ( where main wire harness passes thru firewall ) while trying to start engine , if you notice a change , chances are corrosion has got in and will have to be disassembled , (split the bulkhead connection ) Pull and clean the old brown dielectric grease out , inspect for bad contacts , tighten up and clean contacts carefully , reapply new dielectric grease lightly on the contacts and seal it back up . This made all the difference in cold starting quality , eliminated my hot starting problem and lights were much brighter everywhere in my 73 Javelin . About a 3 hour job for a 60 year old

All good suggestions and will probably need attention, but yes It is totally dead electrically. No lights, no anything. Thanks for the feedback so far.

I bet it is the bulk head connection. Uncouple and reconnect. Them things prolly are corroded from all the years.

I would start by cleaning all the connections in the high current path - at the battery, solenoid, starter, and the ground connection at the engine. Make sure the engine to chassis cable is there and the connections are clean. It costs nothing and should be done anyway since the car has been sitting. Battery cables can look good on the outside while being corroded on the inside. An ohmmeter can verify their condition. Cable resistance should be an ohm or two at most.

Like bigbad69 said above be sure to check the engine to front engine to cross member ground wire/cable. It's on the passenger side near the motor mount.
It's not as heavy as a battery cable but it's necessary to provide the ground return path for all the electrical items that are part of the body. This would most likely explain no lights as well as the starter relay (solenoid) not working |

Once had a 73 AMX and the alternator died and fried the battery. Replaced the alt., voltage regulator and battery and guess what... nothing. We tested the wiring path to the starter relay and discovered a fusible link in the harness. Replaced it and ran fine. The TSM will show you where to look and the type you need. They were available at most parts stores. Good luck. Dave
