Hello,

I get Battery Light + Exclamation on Dash. I feel the alternator has had it but wiring on vehicle is problamatic so cant be sure. Is there a way I can check that the alternator is working?

When I measure voltage across battery starts at 15 and made it way up to 18.5v. When putting full beam am seeing a 1v drop.

Previously my battery was low I'd charge it drive andit would go flat.. hence why I assumed it was alternator ( or wireing to it) I charged it over night and today it didnt stall when it was running. that when I measure voltage across the battery.

As I said I am seeing both battery and exclamation light on dash.

Hope soembody can advise..

18.5 volts is way too high, and could cause other failures too. Is your meter accurate?
You should get the voltage checked accurately urgently. If it is 18.5v then regulator, which is usually built into the alternator has failed.
