My recently purchased TR7 V8 has Newtronic Electronic Ignition fitted. Anybody out there fitted the same unit & still have the original installation instructions/manual. If so a scanned copy would be much appreciated. Thanks, Ian.
A further question for any body able to help. Is the cover of the Newtronic Module removable? Looks like there are a couple of tight fitting push in blanking plugs which may or may not be able to be prised out to uncover fixing screws. See photo. ( Not my unit but a photo copied from the interweb for reference purposes) I've tried poking with a sharp implement but to no avail. Don't want to force the issue & break something.

Thanks for answer. Reason for wanting to remove cover is I assume the unit is screwed to the bulkhead & I may want to remove it at some point, to reposition it or clean/paint panel behind it. Not an urgent requirement but I like to be prepared. There are no external fixing screws visible.
If you dismantle the unit you will need to replace thermal paste between the power transistor and the metal heat sink. I got mine from RS Components - 1805306 Silicone grease, 1.4 W/m K, 20g which cost about 10 quid inc postage
The Pirana/Newtronics units can suffer from bad solder connections (aka dry joints) which can easily be sorted with a few minutes soldering. This turned out to be the problem with mine and I have had reports of three other units suffering form the same issue.
Procedure is as follows:-
1) Remove PCB from black plastic cover
2) Re-solder all the soldered connections with a small soldering iron & suitable solder (with flux)
3) When finished, spray PCB with clear varnish to protect components
4) Reassemble unit applying thermal paste to the metal cased power transistor.
