Oil Level Test Switch

[gait]

my oil level test switch on FG649 stopped functioning a couple of days ago. There's plenty of oil showing on the dip stick. I used to hear a click as the test light changed to green. But alas no more. Zilch.

So far I've checked the switch (it works ok with zero resistance when pressed). Virtually no volts across the switch when open.

Unfortunately all the circuit diagrams I have don't have an oil level test.

Anyone any idea what the circuit looks like?

HI i hope this helps you to solve the problem.

If you can't read this well enough go on our picsaweb.google link below and you can enlarge it.

thanks muchly, it helps enormously to have a clue what's in the circuit and how it works and roughly what volts to expect.

Thinking back, the interior cab light stopped working about the same time - just replaced blown fuse for "room light". All working again now.

Beats tilting the cab to check the oil (though I do that periodically "just in case").

Many thanks.

I like the idea of an oil level indicator in the instrument cluster.
It's a pity that Fuso, in their ultimate wisdom, have decided not to continue this feature in newer models.
