Sadly, it's not just rubber items. Just over a year ago I bought new gauges from Rimmers when there was an offer on, one of which was a fuel gauge. Last week, I finally got it out and started to sync it through my Spyda Fuel Gauge Wizard to my VDO dip senders. Needle shot immediately to full and beyond and then smoke started coming out. I should probably have checked it first but, hey, it was brand new. Anyway, a check with the multi-meter proved it to be faulty.
I was doing this on the bench so not an issue. Disconnecting everything was not a problem but if I had done this in a car, put it all together and assumed everything would work, I hate to think of the consequences.
Phoned Rimmers to complain and was told it was about a week out of warranty. No offer of refund, no offer of small discount, not even the 20% saving that I got when I originally bought it!
Happily, the original gauge still works even through the Gauge Wizard.
Yes, Frank. It's the original Jaeger and yes, I was aware of the need to earth it. My test set up to calibrate the Gauge Wizard had the case earthed too.
First read about it when Gary used one on his Peerless and did a write up in PC. I think he was using new senders too but can't remember the type.
Anyways, needing to get a VDO dip sender to talk to an old Jaeger gauge, I felt this was the way to go.
Long and short. It can get any sender to talk to any gauge. Also works with water temp senders to gauges too. Can be set up to include low fuel/high temp warning lights and a host of other features I don't need.
I've spoken to Chris, who runs Spyda on a number of occasions now and he's an extremely knowledgeable guy and exceptionally helpful too. Highly recommended.
There are a range of youtube vids where you can watch the whole set up process. Pretty straightforward even for a Luddite like me.
