I have just fitted a battery to the Herald for the first time in 8 years (long restoration with the end almost in sight). When I do, the "indicator light" output of the nice brand new Lucas LRA100 goes to
+12V instead of the expected 0V - I've checked it under load, so it's not just a drift up).A spare LRA100 I have lying around seems to work fine, so it's going in for the moment. Some advice on the dud would be welcome ... is this likely to be the regulator, in which case it's a cheap repair, or is it likely to be something nastier?
