I have a bit of an issue with my Wizard 4jg2 where it overcharges at times. When you start up and idle it will sit at about 14v but when you get out on the road and put a load up it it can peak it 16v + for short moments of high RPM. Things I have tried thus far...
- Looked at and changed charge relay - no change.
- Looked at all fuses under the bonnet and under the dash - no blown.
- Visually looked at groundings around the battery and alternator
- Removed alternator replacing the voltage regulator, bearings and seal - I thought this would have fixed the problem but I installed and still the issue is there.
When I made the repairs and put the alternator back in it now has an intermittent no-charge on start up and the battery lights etc will illuminate on the dash - this doesn't happen all the time and seems to come back online after a wee rev and will stay this way which is weird - has anyone put these alternators back together and had a similar thing? I suspect it is the new bushes not sitting quite perfect but I could be wrong there - I believe this is an unrelated issue to my main concern.
I haven't been driving it to work but the car I have needs to be returned so to get myself to work without any issues I will be turning on virtually everything the truck has to soak up as much voltage, which seems to be doing the trick to prevent further damage to other components but would love to get it back to normal as this is just temporary.
Any ideas would be greatly appreciated - it's got me scratching my head!
