Sent you a pm, by the way, shouldn't discount the sensor that lives on top of the expansion tank.

Testing the Level Sender Circuit

Moved to last post

Thanks for your help so far. I took the van for a drive today (light blinking away merrily) and filled it with lpg. I noticed when driving home that the light was not flashing any more. There had been lots of roadworks to get through, so the engine was pretty hot - I'm wondering if the heat has affected it?

Later on, I poked around with the multimeter and things were back to the same as before - that is, blinking light no matter what i do. I reckon its not the sensor, as the light keeps blinking with the wires disconnected. So I guess the next thing is to find out where the wire is faulty.

I might contact you about using the multimeter as its instructions are a bit vague.

Thanks,
Donald.

Testing Coolant Circuit Wiring

Moved to last post.

Hi Angelo - that is really good information Thanks!

But

Verify by placing a multimeter set to ohms and measure the resistance across the pins of the coolant level sender, if it reads anything other than an open circuit with the correct level of coolant it is faulty.

Know how to set to ohms....how do I know if it is reading an open circuit...sorry for dim question...jsut mastered reading volts!

Also... I have the antique fuse box. You know, the one with bullet fuses....any ide where I might find that control unit?

Hi Em, think I will have to contribute a wiki article on using a multimeter

Any way, look at your multimeter and look for the Omega symbol (looks like an O with a line under it. You should see a range of numbers with K or M after them, set your meter to point to a number such as 2K (this means you can measure resistances from O ohms up to 2000 ohms. Rotate the dial and point to 10M and you can measure resistances from 0 ohms to 10,000,000 ohms (you won't need that too often!) You might also have a little music symbol which will cause a tone to be heard when you touch the two leads (black and red) together. This is useful for checking short circuits and testing fuses, no beep = duff fuse or an 'open circuit'.

Sod it (oops!).....will do a duffers guide tomorrow.


As for the location of the Coolant level Control Unit 43, this should be with all the other relays on the fuse box and marked 43. (third one from left)

Hi Em, sent you a PM as the level control unit is somewhere behind the dash, not on the fuse box (on earlier models).

Here is a link to a multimeter tutorial, plenty of others if you Google. (May save you a bit of typing AngeloEvs).
Like your detailed explanations though, please don't stop them coming.

Grun,

Thanks!

will be printed off later and laminated, and stored!

y didn't I think of google...I google just about everything else

Testing The 'POD' (moved to final post)

Angelo,

that is a truly fantastic right up.....and needs to be wiki'd!!! Many, many thanks! Got have a chance at getting the circuit tested now! Had a brief hunt for the elusive control unit...will let you know when I track the little whotsit down!



And for your next trick???

sorry if anyone printed it as I have updated it below and removed the unecessary, and corrected the mistake concerning the Level Sender readings.

Dumped here.....to long for a thread!
