startomatic control box

[Jase1988]

hello i have two lister startomatic control boxes. one is in good shape and less complicated than the other as in does not have the large capacitor in the center. the other is in not such good shape but has the large capacitor in the center  and two extra metal fin type things. my question i obviously i want to use the good one. so are the diffrences in boxes just diffrent years of production and will either of them work? i have seen on google images there are two diffrent boxes.. many thanks Jason.

Hi Jase, yes there where a lot of different SOM control panels. The very early units had selenium rectifiers/diodes/capacitors and large mechanical relays, as technology improved Lister started using printed circuit boards and modern silicon compomponents. Please post a couple of photos of what you have so we can give an assessment of their suitability. It would also be useful to have some idea of what you are trying to achieve.

Hi , I am having trouble with my SOM on a 1975 Lister 6KV gen set. The engine runs and starts fine with the solenoid override pin in, but when I turn of the mains power I do not hear the main replay click on to try and start it. I have replaced the override micro switch which in the past has proved to be a problem, anyone know of any trouble areas to look at? thanks for your help
