nigethomas Posted May 18, 2016 Report Share Posted May 18, 2016 Hi there was something else i would need a little advice on regarding starter solenoid. whilst i was turning the engine over at the weekend to try and build oil pressure up the starter solenoid appeared to be stuck on.The only way i could stop was to remove battery leads.The solenoid is new which i brought from stoneleigh from TR shop. The brown wire was connected to the large terminal and red/white to the smaller terminal.The starter motor cable connected up and the battery cable.Is it just a faulty sticking solenoid issue or is something not connected as should be? Any advice on this would be much appreciated. Cheers Nige Quote Link to post Share on other sites
boxofbits Posted May 18, 2016 Report Share Posted May 18, 2016 Hi Nigel I would suspect a faulty starter solenoid. I always try and obtain a used or NOS part if I can (they weren't made in China for one thing!) You can probably find one on EBay, and if the rubber tit has perished you can buy them new from usual places. Regards Kevin Quote Link to post Share on other sites
nigethomas Posted May 18, 2016 Author Report Share Posted May 18, 2016 Hi Kev Yeah thats what i thought but i only turned it over once and it stuck on straight away.You would think it might have lasted a bit longer than that Nige Quote Link to post Share on other sites
BlueTR3A-5EKT Posted May 18, 2016 Report Share Posted May 18, 2016 Give it a good dosing with a suitable freeing agent line Plus Gas to see if it frees up. I have rescued a few in my time with this method. Once you are happy it works correctly and the external manual button does not stick or jam. Give it a brush externally with a brass wire brush to remove grot and other residues. - Then it looks like a bought one. Peter W Quote Link to post Share on other sites
nigethomas Posted May 18, 2016 Author Report Share Posted May 18, 2016 Hi Pete The solenoid is new its first time i used it Nige Quote Link to post Share on other sites
stillp Posted May 18, 2016 Report Share Posted May 18, 2016 Mine was getting a bit intermittent when operated manually, so I've replaced it with one of these: http://www.ebay.co.uk/itm/LUCAS-SRB316-76702-2ST-12v-push-button-starter-solenoid-GENUINE-/161725228219 Also changed the lead from the battery and from solenoid to starter motor. The engine now spins a lot faster! Pete Quote Link to post Share on other sites
nigethomas Posted May 19, 2016 Author Report Share Posted May 19, 2016 Hi Pete Thanks for the link.I think i will buy one of those.Ive already put new battery and starter leads on. Cheers Nige Quote Link to post Share on other sites
Graham Harris Posted May 19, 2016 Report Share Posted May 19, 2016 Nige,i put a new solenoid in my 3A and had the same problem but it only happened once and only when i manually operated it from the engine bay, works fine from the starter button on the dash.

nigethomas Posted May 19, 2016 Author Report Share Posted May 19, 2016 Hi Graham I havnt got the ignition switch connected up yet so just using the button on solenoid to turn engine over. Might just have look inside first before buying another.It did work correctly when i banged the outer casing with a srewdriver few times then failed again.

RogerH Posted May 20, 2016 Report Share Posted May 20, 2016 Hi Nige, I'm not sure you can look inside without destroying the solenoid. As for operating it electrically - simply run a wire from Battery + to the small spade fitting where the red/white wire normally goes. I think this was mentioned previously.

nigethomas Posted May 20, 2016 Author Report Share Posted May 20, 2016 Ok thanks Roger Nige Quote Link to post Share on other sites
Lebro Posted May 20, 2016 Report Share Posted May 20, 2016 Hi Nige, I'm not sure you can look inside without destroying the solenoid. Roger I think it could be done, I have done a tractor one before now - it was similar construction. I have also done an original TR 3 one, it involved removing the swaged over end, dismantling, cleaning up the contacts with a smooth file, the re-assembling using araldite to hold the end plate in place - on the car now, & working well.

BlueTR3A-5EKT Posted May 20, 2016 Report Share Posted May 20, 2016 If the solenoid jams ON the starter will keep going until.... the main battery cables catch fire and/or the battery goes flat or the starter motor burns out. If you have fitted a battery isolator switch, turning it off would save the cables etc if the solenoid jammed ON. Fit a replacement solenoid for peace of mind, unless you feel confident to delve inside it. Peter W Quote Link to post Share on other sites
