I have a 1996 Adventurer and the Rev counter does not work. I am going to see if I can fix it but does anyone know if a Tacho from a contemporary Trophy will fit and records the revs accurately? Many thanks.

No, sadly the Trophy units are slightly smaller. Should work though, but you'll need to make a new mounting plate (not a bad idea really seeing as Trophy clocks are cheap as chips & easily available).

To repair your original you'll have to cut it open, here's how it's done

I didn't do the ally ring & screws part, just sealed it back up with a hot soldering iron.

You could prise the ring off but it makes a mess, although a few people have done it successfully. I tried it and made a mess.

Here's what you'll find inside -

If you can't be bothered fixing yours and you're just going to throw it away I'll buy it off you :).

Could just be a loose connection. Mine was intermittent for a while but pushing on the wires that go in the back got it going again.

Chaps
Thanks for your thoughts here. I think that before I bought the bike the fault was intermittent but then again perhaps that is a typical feature when the Tacho is on the way out. Appreciate the how to bit also.
If I am about to bin it I'll let you know. I hope that Burren Boyo is right!

He could very well be, remove the 3 pin signal connector and look carefully at the pins - sometimes they push back into the clock body as Sean says. You can pull them back out with needle-nosed pliers. Not a permanent fix but good enough, and they do wobble all over the place - it's from engine vibrations and you'll notice it at between 4000 & 5000 rpm, typically 4200 being the worst spot.

I removed my original clock mount and made my own that mounted from the bottom of the clock housings -



the tacho worked perfectly smoothly, put the original back on last weekend and the bloody wobbling is back, even though I used thick rubber washers :(.

I need to find another solution.

Actually the Trophy(older) units are bigger than ours. Trophys tacho diameter is around 93mm against our 85mm and the Trophys redline starts at 9500rpm.

Check the tightness of the three brass ferrules at the back of the gauge. These ferrules hold the gauge's coil assembly up against the contact pads on the circuit board.
As Arfer mentioned before, the bikes vibration can also cause them to become loose.

Thanks again chaps. I'll set aside some time to have a look otherwise I guess I'll simply do without the Tacho, a first world problem I guess. I'll let you know how I get on.
