Lister ST1 Startomatic Generator help needed please
1956ld1:
Hi all,
This is my first post on the forum so please forgive any mistakes.
Yesterday I purchased a rather unloved Lister startomatic. It was completely seized and the unforgiving climate of the west of Ireland has not been kind to it. Took it to bits last night and have accessed the damage- one very stuck piston. Having accessed the engine I believe all it needs is a barrel kit and big ends. Now the startomatic side of things is another story. I'm quite confident I can get it working again but I would appreciate a wiring diagram but more importantly a diagram of the selector switch and the reset? switch as both are completely shot and I can't seem to reverse engineer them. all the relays are seized solid but I should be able to free them off. Also if anyone has a guide to replacing the diodes and what values to use and in which direction, particularly the one in the generator with a load of wires coming out of it, It would be great. I have (hopefully) included some pictures of the tag and various electrical gubbins. If anyone has spares for these I would be very interested.
Kind regards,
Josh.
I've no clue how to insert pictures so They can be found here: https://drive.google.com/drive/folders/1ablw4uLkdiQhliJGK51p2h58uu--X9KK?usp=sharing

Also if anyone has the two control solenoids that sit on top of the engine to control the decompressor and fuel rack id be very interested in them as they are missing on this unit. I have a similar unit that uses a 240v solenoid connected straight to the output to trigger the decompressor? is that how its supposed to work?

I think you will find the solenoids are like rocking horse poo. hopefully the cct will appear for you
oldgoat:
Aha success. Throw away the selenium rectifiers and replace the with 400v diodes also check the 4Mfd capacitor for leakage and give it a new 50 Mfd Cap. The reset switch is a thermal relay. The fuel solenoid has a double winding you could probably replace it with an ebay solenoid and a microswitch to reduce the holding current

Thanks very much, the advice will get the project rolling hopefully. Any recommendations for the size of the diodes? 1 amp? I took the relay to bits and have a few pictures for any other members to use. it can easily be replaced by a 12v (or 24V) timer and relay.
Kind regards,
Josh.
