Nifty Posted May 1, 2005 Share Posted May 1, 2005 I've been having electrical gremlins ever since I rebuilt the car last year but today takes the biscuit. Was driving along when it started to spit with rain so I switched the wipers on (that had been working previously) and there was nothing. Fiddled about with the switch and fuses but still nothing. Due to lack of visibility and possible thunderstorms I turned round and headed home. Then, some 25 miles later the wipers came on at full speed with the switch OFF and the engine started to splutter before dying (luckily I could freewheel into a large farm driveway off the road). It then transpires that my battery has boiled 🤔 WHY 🤔 🤔 *confused* All I've done since the wipers last worked was remove the windscreen (and therefore disconnected the heater element) and then replaced it. I suspect that the wiper issue is a symptom and not a cause. Please help before I have a John Cleese moment and thrash the living daylights out of the bl%dy thing ❗ ❗ *mad* Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Myles Posted May 1, 2005 Share Posted May 1, 2005 I'd guess that, if the battery has boiled, either you've caused a massive short somewhere (and this would almost certainly manifest itself in burning smells/smoke), or your alternator could be seriously overcharging. Hard to tell which at this distance. Project Scope-Creep is live... Alcester Racing 7's Equipe - 🙆🏻™ Alcester-Racing-Sevens.com Link to comment Share on other sites More sharing options...
clive powell Posted May 1, 2005 Share Posted May 1, 2005 regulator in the altonator has gone causing full amps going into battery unless you have lots of burnt wires the wrong side of the fusebox Link to comment Share on other sites More sharing options...

Mr Locust Posted May 1, 2005 Share Posted May 1, 2005 Sounds like you have 'issues' with the park switch / ignition switched, permanent live feed in the wiper motor too. Ian Green and Silver Roadsport 😬 Link to comment Share on other sites More sharing options...
shn7 Posted May 1, 2005 Share Posted May 1, 2005 Did any lights glow brighter than normal? Always a good sign for an alternator overcharging. I think assuming this is a K series with std MEMS that the regulator will be part of the ECU. Best thing to do is check the voltage across the battery with the engine running. Should be about 14.2 volts. If it's much more then it's surely a regulator problem. Steve. Link to comment Share on other sites More sharing options...
Peter Carmichael Posted May 2, 2005 Share Posted May 2, 2005 Regulator is part of the alternator. Link to comment Share on other sites More sharing options...
shn7 Posted May 2, 2005 Share Posted May 2, 2005 Thanks for the correction Peter. I was working on information received rather than definitive knowledge on that point. Steve. Link to comment Share on other sites More sharing options...
