Voltage and engine varying swinging up and down!
What could cause this, it happened after I washed the car and it was fine on way to work and back/
Its a Mk1, running a 16V on mk2 K-Jet ECU. Could a wet ecu/tci cause it? (noticed some small amount of water on it unlike normal). Screwed Voltage reg? Deceased Alternator?
Ok, i've had a minor prob for ages, after I installed a new voltage reg I have had to give it a quick squirt of revs to get the battery light to go out (stands to reason, to get the voltage high enough to flip the voltage reg I assume). I had assumed that I needed to strip alternator down and clean contacts, but havent had time.
I haven't a clue…

Got to be something to do with the rain. Fan belt has started squealing slightly too. Going to tighten that up, hose the lot in wd40 and see if that helps after the football!
Either that or a new alternator is required…

Would be interested to see how you go with this. I had a new voltage regulator fitted a couple of months ago because the voltage wwas going all over the place.
However, in the last couple of days it swings > 14V when the car starts - only does it for the first few minutes. I spoke to a friend who is an auto electrican and he says it's probably to do with the windings on the alternator. If the voltage is unstable all the time, then he reckons it's the regulator, otherwise windings.
I'm going to monitor it and see how I go.
P.S Thanks for the PayPal email - will sort out tomorrow!!
