Aussie Posted August 19, 2017 Share Posted August 19, 2017 (edited) Not a bad day today so started the Cent without any problem but noticed the tachometer isn't working. I've read all the stuff I can find and it seems that it's just a simple voltmeter connected to a tachometer generator on the front of B (right) bank of the Meteor. Everything else is working. I'm guessing it's just a loose connection but can't spot the tachometer generator from the top of the engine bay and not too sure which wires to fiddle with on the driver's panel (although if push comes to shove I'll pull that apart) so I'm a bit lost! Anyone know how to find/check the tachometer generator end of things, and how to check the tachometer itself? (Bearing in mind that my knowledge of the black art of electrics is pretty basic).

Caddy Posted August 19, 2017 Share Posted August 19, 2017 It's a black device with 2 wires coming out of it. It is on the B bank and is attached to the end of the head nearest the fighting compartment. Think it's really tucked in to the bulkhead Quote Link to comment Share on other sites More sharing options...
Aussie Posted August 20, 2017 Author Share Posted August 20, 2017 Thanks Caddy. Still not sure how to get at it but will see if I can remove a bulkhead plate to spot it. James Quote Link to comment Share on other sites More sharing options...
Adrian169045 Posted August 20, 2017 Share Posted August 20, 2017 (edited) Remove the bulkhead and it's easy to get to. they do have a habit of sheering off the gears I got a couple of spares if you need I also have all the wiring diagrams the wires will be marked cheers adrian Edited August 20, 2017 by Adrian169045 Quote Link to comment Share on other sites More sharing options...
Aussie Posted August 20, 2017 Author Share Posted August 20, 2017 Thanks Adrian, that's great. Trawled through the manuals again last night and found a reference to a junction box in the turret, so I'll try testing at that point first, when i get back to the shed. Should show which end of the system is playing up (or maybe hopefully just a bad connection at the junction box). James Quote Link to comment Share on other sites More sharing options...
Aussie Posted August 23, 2017 Author Share Posted August 23, 2017 A bit of light relief! Checked the voltage of the tachometer terminals (bottom 2)at the drivers panel: nothing. Hit my head crawling around in the fighting compartment but found the junction box on the hull side beside the Commanders seat pedestal Lid off and checked voltage at the Tachometer Generator terminals (2nd and 3rd bottom from left): nothing So rotated the gun to the left to get at the bulkhead panel (the panel above it is the aux gen control) Off with the panel and... If you have a keen eye you'll spot the loose cable hanging down on the left Voila! Cheers James Quote Link to comment Share on other sites More sharing options...
Caddy Posted August 23, 2017 Share Posted August 23, 2017 Got to be a happy bunny finding that, now you've got to fix it. Dunno what spec cable you've got available in Aus, but I'm using TC12 for any desiring up at Duxford as we can't get Unipren Quote Link to comment Share on other sites More sharing options...
