Check all the wires from the alternator are intact.

If the light is going off on the dash once you have started the engine then the alternator is probably working fine, 90% on that.

The ground strap is a must, there isnt a good earth through the bolts for the alt to the block, you defo need a strap.

If this still doesnt work, the voltage regulator may be packed in or a contact gone inside the alt

:(

check the voltage from alternator with a voltmeter, should be 14v if its 0v then check ya earths like ya suspect

ok mate gud luck :thumbs:

maybe the warning light on the unit aint on properly... il check that tomorrow... thats the most likely suspect as to why the light aint on.

il also make up a strap tomorrow.

ok mate, well not sure why u dont have a battery light coming on tbh - do you get any other problems with the xe conversion relating to warning lights??

i know its not charging for sure.... im almost positive its meant to have an earth strap from the adjusting slider to the block where the slider sits on..

it must be that, im just puzzled as to why not light is on....

well i dont know about the xe tbh but im pretty sure theres meant to be an earth strap...if not u can check the alternator by looking at the voltage across the battery under load e.g with headlights on etc

yeah i kinda thought that but would that effect the charging of the unit... possibly... im not sure..

should be an earth strap from alternator top adjuster bracket thing to the block/cyl head

well see maybe ur right... and thats why it aint charging.. im a newbie to there valvers...

i also got this engine in bits so ive had to piece it together..

i thought there was meant to be a vital earth from the alternator to the block?? correct me if im wrong...

its not charging... was driving along in the xe.. quite the thing then she started to missfire. just as well i wasnt far from home as she died as i got into the drive... dam thing aint charging... dunno why it aint, light is fine on the dash. aint on.... totally puzzled.

anyone got any ideas.
i could go and look but im lazy. maybe the positive aint on properly.... i dont have an earth on it thou like some others...cant see this being a problem
