nigethomas Posted June 20, 2016 Author Report Share Posted June 20, 2016 yes i have power to the ignition switch.The wiring is a new loom which was fitted last year. I checked the fuses and they were not blown or anything. Nige Quote Link to post Share on other sites
peejay4A Posted June 20, 2016 Report Share Posted June 20, 2016 (edited) So do you have continuity from battery positive to the green wires when the ignition is on? If not is there continuity to the switch? If you have continuity to the switch then the switch is suspect. Edited June 20, 2016 by peejay4A Quote Link to post Share on other sites
nigethomas Posted June 20, 2016 Author Report Share Posted June 20, 2016 will carry out the various checks at some point this week and report back. Cheers Nige Quote Link to post Share on other sites
keith1948 Posted June 22, 2016 Report Share Posted June 22, 2016 (edited) Hello Nige Agree with Pete that black wires with ring connectors on are the panel light earths and connect under knurled nuts on brackets holding gauges to back of instrument panel. These are nothing to do with operation of gauge which earths itself via sender (thermal resistance on temp gauge and mechanical variable resistance for fuel gauge.) Coming back to an earlier post of yours you said you connected green/black wire to I terminal on voltage regulator. The wire from the regulator to the gauges is light green/green on autowire wiring diagram but green/black in TR4A handbook and green/black on my 4A. So I would say your green/black connection to I terminal is correct. Try by passing all of ignition, fuse box etc by running a wire direct from battery +ve to B terminal of regulator. Earth body of regulator directly to -ve of battery. Run a wire from I terminal of regulator to temp gauge. Connect a car bulb (to give some resistance) between other terminal of gauge and -ve of battery. Needle of gauge should move if regulator is working. If it doesn't then regulator is faulty. If it does work then look at wiring connections. Keith Edited June 22, 2016 by keith1948 Quote Link to post Share on other sites
nigethomas Posted June 27, 2016 Author Report Share Posted June 27, 2016 Hi Keith / Pete I spent a bit of time on the tr on saturday afternoon.I decided to look into why the vehicle does not start by ignition key first.I checked continuity for the red/white wire which leads to the starter solenoid from ignition switch all ok.Also checked for when the switch was in start position and that to was ok.I decided to bridge a wire across from the solenoid where the battery cable connects to and the red and white wire terminal.Nothing happened which must confirm i have brought yet another faulty starter solenoid GRRRRRRRR Nige Quote Link to post Share on other sites
Lebro Posted June 27, 2016 Report Share Posted June 27, 2016 Make sure the solenoid it's self is earthed to car body. Bob. Quote Link to post Share on other sites
nigethomas Posted June 27, 2016 Author Report Share Posted June 27, 2016 Hi Bob is it best to run a wire from the body then to the solenoid? Which terminal would the earth go to on solenoid? Nige Quote Link to post Share on other sites
Lebro Posted June 27, 2016 Report Share Posted June 27, 2016 The metal body of the solenoid would normally make contact with the body where it is bolted on. It's possible that paint may be blocking this connection. Bob. Quote Link to post Share on other sites
nigethomas Posted June 27, 2016 Author Report Share Posted June 27, 2016 OK thanks Bob Nige Quote Link to post Share on other sites
nigethomas Posted July 3, 2016 Author Report Share Posted July 3, 2016 Just to let you all know I have temp gauge and ignition switch all working OK now.thanks for all advice given on this. Nige Quote Link to post Share on other sites
keith1948 Posted July 4, 2016 Report Share Posted July 4, 2016 yipeee!!! Keith p.s. what exactly was the problem in the end? Quote Link to post Share on other sites
nigethomas Posted July 4, 2016 Author Report Share Posted July 4, 2016 Hi keith Well the ignition switch was just a case of a bad earth so cleaned up and re fitted solenoid. The temp gauge i just connected all the black earth wires up as there was one that was hanging loose still and it worked.ive not checked fuel gauge yet as no fuel in tank.

silverfox4 Posted April 26, 2020 Report Share Posted April 26, 2020 An old thread but seems to be the best one to bump for my rather simple query. I purchased this solid state voltage stabilser for a TR4A and I notice that the Instrument terminal "I" is female spade and the Battery "B" a male spade - is this right, as it looks as the original on the car has male terminals only.

Richard Green 54 Posted April 26, 2020 Report Share Posted April 26, 2020 This is the original voltage stabiliser I have just removed from my TR6. It has both male and female connectors. Quote Link to post Share on other sites
silverfox4 Posted April 26, 2020 Report Share Posted April 26, 2020 Thanks Richard, now I can try and stick my neck in there. Cheers, Alf Quote Link to post Share on other sites
silverfox4 Posted April 26, 2020 Report Share Posted April 26, 2020 Well this is a pain - my voltage stabilizer only has male connectors. Is a matching solid state version available for the TR4A? Grrrrh! Cheers, Alf Quote Link to post Share on other sites
