Possible Alternator problem

This moves from 13 then in to the red and fluctuates back and forth any ideas

Thanks Simon

Not sure you should be taking pictures at 50 mph😄

That's why the second picture is upside down......

Thanks Simon

2 likely causes:
- faulty charging regulator
- faulty gauge

Operating at significantly over 14.5V will cause excessive electrolysis of the battery electrolyte -> early failure and possible fracturing of battery case. Also may to cause other damage to electrical equipment if their operating voltage is exceeded.

The gauge could be verified with a multimeter

What makes you think I took the picture

2 likely causes:
- faulty charging regulator
- faulty gauge

Operating at significantly over 14V will cause excessive electrolysis of the battery electrolyte -> early failure and possible fracturing of battery case. Also may to cause other damage to electrical equipment if their operating voltage is exceeded.

The gauge could be verified with a multimeter

Thanks Jonno that makes sense

Don't think its the Gauge when its goes in to the red the electric windows work twice as fast

What do you class as significantly, Mine charges at 14,5 volts an has been since I fitted a 80 amp alternator the battery hasn't exploded and I have not had any equipment damage. As far as I know my unloaded charge rate is not abnormal. PS, the alternator has been on there now for 5 years

Thanks Graham,
I've amended the voltage level (though personally I prefer it to be closer to 14.2V). However, at the levels shown on Simon's photo, I would have concerns of catastrophic failure as the rate of gas production could exceed the capacity of the pressure relief devices, apart from the hydrogen being produced in proximity of ignition-leakage sparks. Hopefully, the fan would dissipate this, though if the VC has been replaced with an electric fan, this may not be running .

I ordered a higher output Alternator from E.J. Wards and it is being brought out to me on the 31st of this month by a friend.
Would this be a similar one to what you have Graham?, don't know what the exact rating on it is, but it may tell me when I get it.
Hopefully when it is on, and coupled up with the new 80amp battery I bought plus my repaired petrol tank, all will be well gain.
