April 1, 201115 yr Anyone ever lose elect to your front wire harness? The one that goes to the carb, oil pressure and temp sending units in the engine compartment.If so, what was the fix?
April 1, 201115 yr What do you mean by "lose electricity"?? The sending units are ground circuits. The carb has a couple hot leads for the choke, idle cut, and bowl vent solenoids..... have you checked the fuses? And no - I've never seen a problem with all of them before. There are typically some intermittant connectors that connect the manifold harness to the vehicle harness.... I would check those. GD
April 2, 201115 yr Author No power to the wire harness that connects to the carb, oil and temp sending units on the engine. Continuity throughout the harness. Pulled all fuses, all looked fine. I took the car to a shop and $90 later they said I needed a new carb. In the process of troubleshooting I connected wires to the plugs going to the carb and found that there was no power getting to them. When I hooked up an alternate power to the harness the car ran fine but all the lights in the dash stay on. Swapped the key assm. with one I know works but no change. Didn't see or smell any burnt wires under the dash. Headlights and turn signals and horn work. Scratch my head! Edited April 2, 201115 yr by 3crows

April 2, 201115 yr when you hooked up alternate power to the car, all dash lights on. check or replace your alternator with a good one.
April 2, 201115 yr Check the fusible links if you haven't done that already. If they are ok then make sure voltage is getting to all the fuses. Does the engine start if you don't apply power to the areas you mentioned? If not, the Ignition Relay may be at fault.
April 3, 201115 yr Author Alternator works fine. Fusible links good. Engine starts and runs with idle turned up but rough until alternate power applied. Then, of course the idle is too high once the carb solenoids work.
April 4, 201115 yr the carb harness grounds to one of the intake bolt. check that is is connected, as it is easy to miss if the intake had been off.
