Yeah, like this

lets be fair about this one...

the electronics hes adding dont actually control anything, they just report on whats happening, in the event of a total electrical failure the cranks still going to turn under power he just wont have all the info on hand.

I do wonder about how these electronic things interact with each other. A mate has a Discovery that had the three amigos and as usual nothing could be found wrong with the three items. He just taped the lights over and kept operating. A couple of years later his brake lights stopped working and the problem was found to be a faulty switch. This was replaced, the stop lights resumed operation, and the three amigos went away. My Falcon ute refused to start one morning. The problem was a blown fuse in the interior light circuit.

Hi,
Now that is just being really silly.

cheers

Holden cruze. If a brakelight blows and its an auto, you can kiss goodbye getting it out of park!

Nope, that's the smartlock circuit, Brian is correct, falcon no go without interior light circuit

A lack of continuity! meter reveals open circuit!

Yesterdays job for me was to make a EFI 3.9 V8 Auto Disco run for Graham. The budget allowed for five hours work, armed with the multimeter, faults found were.

Loose non-standard wiring inside the dash, that had been powering something since removed, had shorted out, removed this wire altogether.

Blown 60amp link in fuse box under bonnet, found using the voltage reading mode on the multimeter, the fusible link was robbed from Fred ( Fred is a disco that's now the laughing point of friends of wrinklearthur, but that is another story. )

Tried to start, the auto selector is way out of whack,( lots of adjustment required, ) found the spot to use is between R and N.

Starter motor now turns over, but the engine won't start, checked for spark using the coil lead to the engine, no spark, so moved to the coil.

Using the trusty multimeter again, looked for voltage at the coil - none except when the fuel pump first ran. So why was there no voltage getting from the ignition switch to the coil?

The coil on this car is mounted along side the radiator with the terminals face downwards, so fiddling around, a wire seemed to be loose underneath but out of sight, the coil was unbolted and ---- here was a wire not pushed onto its terminal.

Wire on, coil bolted back in place, selector in the wrong spot and tried the key.
Oh my! The engine fired, The smoke! The noise! Bits flew out from under the bonnet! and I jumped a Toyota, ( but I didn't use the meter to measure this. )

So engine runs.
The bits were the failure of Graham's attempt to repair the fan blade successfully. The smoke was oil in the manifold that was left over from the donor car's demise and the noise!!!! was the unmuffled exhaust from the engine pipes.

Time spent less than a hour, using a meter.

Thought I'd update this one with my progress on my 'electronic project', check out these videos
