Hi guys,

 

Just had a new alternator fitted on 92 import the car started fine when it left the garage then I droke it 30 miles no trouble. But when I went to start it after 4 hours there was a flat battery. Any suggestions?????

 

Thanks

measure voltage accross battery terminals while the engine is running.

should be close to 14 Volt.

 

anything lower then 13.5 V and the alternator is not working/charging or there is a wiring issue.

the battery might be goosed, collapsed cell and not holding charge

 

do the test as above that rules out the charging system, failing that its a dead battery or a drain somewhere. with the ignition off, disconnect the + terminal of the battery and put a Ammeter in series with it and see if there is a large drain (i dont know the standard drain for the clock and stuff that runs with the ign off) but it shouldnt be more than 1-2A. if its more than 10A tho it will destroy most Ammeters so if there are fairly big 'popping' sparks its probably too high for the metre, but if u can rub the terminal on the battery post and it sounds 'gritty' with sparks then its probably ok. hard to explain, but there u go

then if you find a high drain then its a case of checking the alarm,boot light etc... till you find the cause

...how much did you pay for the altenator?

Where in Wales are you from?

From Abertillery but in Newport most days for work, it seems to be better now. The connection was poor so it died

Was just wondering why we haven't heard anything from you as you are local?

Please read this from the WALES section -
