Tacho stopped working

Gregg B · Jan 19, 2012

Hello all,I have a DS4510 and the tacho/hour metre has stopped working,only have about 150 hours.Any ideas where to start looking? I know it is probably a simple fix but I know someone here will make it easier.Thanks Greg

Check to make sure the connector didn't come off the sensor. That happened to me (don't know how) but I pushed it back on ans all was well.

Thanks for that, the sensor you are talking about is up in the instrument panel I assume?

The sensor is near the front end of the engine, right side (at least on mine which is a DK45S). It's a magnetic pickup that's triggered by a gear or flywheel that's on the crankshaft or camshaft. Possibly #2 in this illustration:

Gregg,

if you haven't got a downloaded Service Manual for your DS4510 it is available free from the PFG download site and is of a high quality.

I just checked my copy and there is a colour photo of the sensor, it's location as well as all the technical data on page 11-25 of the electrical section.

Couldn't work out how to copy the page for you but here is the link.
