startomatic

(1/8) > >>

vegoil:
my startomatic has stopped working it has been starting and stopping when a load is switched on or off.
now it will not auto switch on. the only way that I can get power from the old Lister CS8/1 is to hold up the exhaust lifter put the switch on the control panel to manual and push the start button if you get what I mean.
I think that it may be a capacitor 50uf 350v DC
has anyone had this happen to you?
I will try to put on photos!

mike90045:
That cap looks in rough shape, so a replacement would be the first thing.   But I don't know if it's in the starting circuit with that high of a voltage rating.

oldgoat:
Throw that Cap away and replace it with a new one.  That cap stops the start relay from chattering while it is running and burning out the contacts. Replace it with with a 50 uF  400 volt cap.

vegoil:
Can I put in a AC/DC or AC or dose it have to be DC only

BruceM:
Either is fine but a DC electrolytic will be cheaper and can do the job. An AC rated (metal film- motor run type) cap will be much larger and more expensive.

I don't have a SOM, and don't have a wiring diagram for it.  The question might be why did that cap fail...if it's what's causing it to not start now.
