no luck on the series 3

#1 Post by larry emrick » Sun Oct 23, 2022 5:55 pm

Tried all the suggestions to revive Pippa's series 3 with no luck. Still no power, no lights. Even the alternator light does not go on when I turn the key. Could the ignition switch be at fault? Would that prevent the lights from coming on?
The only ground strap I can locate is the one from the battery to the block and I have removed and cleaned it twice. The manual and internet chat refers to others but I cant find them. Fuses appear good. Battery strong.
Thanks for your suggestions, Larry

PS:

One hugely reliable source said there is a ground "under the air filter canister" which I look off, but there's nothing that looks like a ground wire or strap.The solenoid tested good with a tester.

Have you tried bypassing the ignition switch? If everything is dead I’d be looking at the ignition switch for sure.

Electrical troubleshooting is a systematic process to find where it is and isn’t getting through to. While some common pinch points like grounds or certain components will fail and are often the cause, relying upon this type of guessing to diagnose may result in missing the true cause. The best way to troubleshoot electrical is to get a wiring diagram and begin following the circuits to find what isn’t working. In this case, the ignition switch will control power to a number of switched circuits including the ignition system, so it will be a good place to confirm power is present and the circuit is functional. From there you can work through the individual circuits to find the problem.
Shortcuts in electrical troubleshooting may fix part of the problem and miss the rest, so thorough careful review is necessary to solve all the issues.
Failed components, corrosion, bad grounds and broken wires are all common things to find, but aren’t always obvious and may only be detected by careful checking of the entire circuit.
The good things with Series trucks is they have relatively simple electrical, so are much easier to troubleshoot than more complex electrical systems, the bad thing is their aluminum alloy bodies and Lucas electrical parts are known to cause issues.
No silver bullet here, but careful circuit testing will reveal what the cause is.
