Hi all
New member here with some newbie queries.
I've just bought a Lister ST1 with Brush SCTF117 3kVA 1ph alternator/starter. It looks like it has practically zero working hours because the oil filter is the original with the original still unbroken green paint on it. Other signs are that there is no sign of the generator bearings ever having been greased, and zero wear of the brushgear. The air filter and housing is still clean. Oil on the dipstick is clear and golden. So far so good.
But it does have some (hopefully minor) problems, and I'm hoping someone can help........
I've started it first by hand, then on the battery, and it gives 230V no problem, but doesn't charge the battery on low or high charge settings. Inside the alternator brushgear enclosure the original selenium rectifier is still in place and I will change this for a silicon bridge rectifier. The small wirewound resistor across the rectifier appears to be intact, but the larger item under the opposite cover has two broken clamps. I'm thinking I will make replacement clamps out of some sheet brass.
So my questions are.
- Does anyone have an owners manual and could send me a PDF of it?
Is wiring diagram E9840256 included in the manual?
If not where can I find one?
Is there a regular reason why the battery charge circuit won't work, before I spend too much time checking it all out. I could use a battery charger, and will use a solar float charger, but would prefer to get it working.
Does anyone have experience of fitting an AVR to these sets, as I understand they don't cope well with low power factor loads in their original setup.
What does the larger resistor in the brushgear enclosure do?
I've already read a bit on this great forum, but most of the posts were a while ago, so I'm starting a new one.
I'm an electrical engineer so I should be able to suss it all out eventually.
Anyway, thanks in anticipation.
Colin
