Erratic behaviour with Tachometer, sometimes works, other times dead. Same with some other gauges. Fuel Gauge stays on 1/4 tank even when empty. Not a fuse or relay problem. Wondered if an inherent fault or electrical short anyone knows about?

This is my 1st post. Great site, great Z cars. Anyone else from Auck NZ?

Re: Tachometer, Fuel & Oil Gauges keep stoppin

Get a Factory Service Manual. They show up on eBay occasionally. In the meantime get a Haynes manual # 28014.

As for your problem:

Remove the negative battery cable.

One by one remove the fusible links and clean the contacts and replace them.

Do the same thing with all the fuses in the fuse panel. Bend the fuse holder clips slightly to ensure better contact.

Replace the negative battery terminal.

With the engine running put your hand on the fuse panel if it is hot to the touch you probably have dirty connections in the fuse panel or the fuses that are installed are not the correct rating amperage.
