Well the starter is in at an auto elec. Looks like its given up the ghost. I gave him the spare I had in pieces to see what he can make out of them. Does anyone have any experience/solutions if I can't get it rebuilt locally? Obviously can buy a new unit from OS but if something else 12v bolts in it might be a shove in that direction.
12V or 6V??
These starters are bog standard simple devices and usually pretty reliable.
Post what you actually need and see what emerges.... I imagine quite a few people in our Register have spares, for example...
