SIII Ignition Switch--High Failure Rate...

I don't think there is a buyer or a seller, a friend of mine sent me the link, but looking at the dates and the address I think the ad itself is a "joke" as well. It did make me smile though.

But you need this "kit" to make it work.

I don't think I'm out yet...There always seems to be plenty of that left in my electrical system.

The Q&As are as funny as the auction. I had a bottle of Lucas Smoke for years, but gave it to someone as a gag when they burned up their car.

Oh, believe me...I'm super-familiar with the electrical system in my 109. Just wondering if anyone else has gone through ignition switches as fast as I seem to be.

I don't know about the Series III switch but a Series II combination ignition/lead lamp switch is designed to only handle about 13-14 amps though the ignition part of the circuit. Could a SIII have a low rating too? Do you have anything that draws more current than a stock electrical system? If yes you may be overloading the switch current rating.

I solved my problem by adding a relay. No the only thing the ignition switch powers is the main power relay which in turn runs all the switched electrics.

Just a thought,

I can't think of any extra loads on that switch...My glow plugs are on a relayed circuit as are the 4 Hella 500s. Being a diesel, I've got a higher-powered starter, but that shouldn't matter as it's only the solenoid circuit that goes through the ignition switch, not the power to the starter motor itself. So I think I'm gonna say "no," nothing extra through the switch.

I wish I could remember where I got the replacement ignition switch 4 or 5 years ago. That might tell me something, as I was occasionally ordering from a supplier of questionable [quality]replacement parts back then...
