Even using the beeper... if i put the terminal on the left side port, nothing... on the right side port, beeeeeeep.

We have a single fuse inside the meter, so it's not like it's a dual feed fuse one for each side... just the one. But i can't get anything measuring on that left hand side no matter whether we do anything at all. So i think it's a dodgy meter.

I'm not going to head out and get one today though that's for sure.

It says on the meter that there are 2 fuses. 10A and x00mA.

If you can find a second one, you're better than me... but anyway, i stole another one off a mate which seems to work well.

For some reason I can't share a link but if you Google 'how to check and change fuses in your multimeter' by Justin Miller he shows where they are in a Fluke which looks similar to yours (and how to check the fuses). There has to be two!

LOL for today, it's so far down the list of importance it's not even worth consdiering, whether my £6 Ebay multi meter gets replaced or goes in the bin isn't really a massive worry.

A bigger worry is the fact i'm supposed to be taking my nice new van to Silverstone next week and Morzine on Thursday.

YOu're missing him being 70 miles away and me having to get the van to him.

But anyway...
Working with @Couchy and a different multimeter this time... the 0.0 earlier was a red herring.

I've been working with my auto-techs on this issue.
With the negative terminal connected there's a parasitic draw of 2.04a
Going through the fuses 1 by 1 removing them to get it to drop there's a drop to 0.7a when i remove the 25a fuse from Fuse block F35 and fuse 25 which is designated as Trailer Recognition Unit.
None of the others seem to have an effect. But even dropping to 0.7a is still higher than i'd expect it to be sitting at.

However the van does start now and is sitting idling on the drive....

Dude, it's like £3.50 on aliexpress with free guaranteed yesterday shipping, this is literally a million miles away from Fluke territory

MingtheMerciless wrote: Mon Aug 15, 2022 5:57 pm Just to throw a further issue into the works, modern cars/vans seem to spend a good few minutes after you turn them off doing electronic house keeping for want of a better phrase so it might pay to turn the van off and measure the draw an hour or so after that.

The trailer recognition module appears to be something to do with towing a trailer with LED lights, from a quick google. No idea what it does, does the van have a towbar?
The 0.7 Amps, was the interior light on when you were testing? That’s about the number for an interior light or two.
