Hi Guys,
Major electrical foibles have landed! Car in question is a '69 3500S.
When I have power on the car (battery earth cable connected) the ignition- and oil warning lights come on, fuel level indicator rises like it would when you switch the ignition on. Electric fuel pump has a seperate switch but the switch is powered so in theory in would be powered as well. When I start the engine the warning lights go out and everything is normal. Alternator charges (says the ammeter). When I want to turn the car off with the ignition key the engine keeps running....
Which implies that I have 12 volts at the coil all the time! Either through the starter solenoid bypassing the ballast resistor wire or through the tacho and through the ballast resisted wire! Tachometer doesn't work as well (but this could have another reason due to electronic igntion being fitted to the car).
Equipment -
- ACR altenator with a bypass of the Lucas 4TR and 3AW ignition relay. 3AW bypassed brown/yellow to brown/black. 4TR bypass in strange, how should it be done? Altenator has 3 wires going in (or out).
- Electronic ignition (Lumenition) with the tacho on the negative side and the non-ballasted wire from the solenoid on the positive side (?)).
- Measuring 12V at coil between negative side of the coil and an earh.
- Recently changed the fusebox with another original fusebox (wires checked, checked and checked, its ok).
- Recently changed ignitionswitch/barrel/steering column lock for a NOS NADA one, old owners laziness to hand over extra keys and general flopiness of the keybarrel after 43 years.
Really puzzled :roll: ! Any help would be appreciated.
Kind regards,
Andries
