Broken Rev. Counter/Trim Gauge

[chorscroft]

The rev. counter and trim gauge for my 50hp etec do not seem to be working. When I start the engine I get lights on the main trim gauge, but the needles on either of the gauge do not move at all.
Is this a fixable problem or will the gauges need replaced?
Were would I get replacements?

Regards

Double-check the wiring for this - in case you have a short, or the wires are chaffed in any way. Replacing them should be a last resort - until you've checked out this first.

my rev counter stopped working a few weeks ago , the warning lights etc are there just no revs . Trim guage not effected though .

I asked on the etec forum and got a reply sugesting that it was more than likeley my rev counter if the lights are still working .

Yours does sound like a wiring fault to me with both guages effected .

Problem now is getting the supplying dealer to sort it out , they don't want to send me a new rev counter untill mine is certified as faulty , but they are in Brum and me in cornwall .

It's been a while but I'm finally getting round to fixing some of the minor things on the rib and I'm now onto the gauges.
I've checked the wiring and it all seems to be fine so I'm presuming the gauges are broken.

I'm not concerned about the trim gauge but would like a working rev counter.

Where could I get a replacement gauge or could I fit a third party rev counter?
How would I go about this?

Cheers

before replacing the gauge check you have 12 volts feed and good earth to the tacho, then check the signal wire for ac signal with an ac volt range dmm or frequency range. if both gauges don't work and failed together then theres a 99.9% chance its the power supply or return that are at fault. checking this may save you a lot of money

Hi Conor, I've had both those gauges lie down last season too, both had to be replaced. Redbay replaced the Rev counter under Warranty (I collected it in Ballycastle, so supplied locally) and got a second hand trim gauge from them for 25 squid. I suspect that the counter will run to major money

Can these all be checked with a standard voltmeter?
Also the etec gauges seem to be plugged in via connectors - Do I just unplug the connector and measure the pins?
