Evenin' all.
My/exJohnnyB's Hilux has this nasty habit of deciding not to run whenever it pleases. 2 of the 3 times this has happened to me now, the charge light comes on. Car has an external voltage regulator and i cant remember if John said he had replaced it or just sent it a smily face.
The motor will run fairly sweet and pootle about with no troubles, then nek minnit/next day it will just instantly run lumpy, refuse to idle and refuse to fire at all if the throttle is opened too far. So to me, this sounds like an electrical fault.
When the trouble occurs, battery voltage is 12v. Resistance between block and negative terminal of battery is about 30ohm (.5ohm with engine stopped) and alternator is spinning away. The last 2 times ive just got frustrated, left it alone and the next day it runs perfectly again.
Ive inspected HT leads, coil wiring, voltage regulator wiring, body ground points and alternator connections. All of them have been sub-standard but there doesnt seem to be one thing thats causing the problems. I would just leave it alone again but would really like it to make it to pit-stop tomorrow morning so i can have an exhaust fitted.
Open to suggestions on what to check gents. I know absolutely fuck all about external voltage regulators so dont even know where to begin.
