possible causes bad earth

Alternator is easy to test, voltmeter across the battery with the engine running. Should be looking at 13 plus volts easy.

Bootlight could be checked with the seat down or by dropping the back seat down.

Battery, is there any electrolyte in it? I replaced the battery on my Ibiza and when I took the old one off I noticed it was well low on fluid. That was pretty dead after Christmas and I had to bump it backwards off the drive.

Just charging it up doesn't prove that it's any good.

If you have volt meter you could check the current flow with the ignition off. Set the meter to amps and put it in line with the earth lead. Don't turn the ignition on cos most meters can only handle a small current. Maybe a few amps tops.

ok the alternator is fine then bc microtech says it charges at 13amps

i know the car has always has a bad earth how can i fix that??


what would you guys recomend ive had bosch batterys and charged two in three years??

Unplug the stereo altogether. To check the earth lead use your meter on OHMS. and see what it reads between the engine and the earth terminal. A bad earth won't flatten your battery but would reduce the charge voltage.

I understand, hope you have a fuse right by the battery!! Take the fuse out and see how it goes.

Have someone check the battery out. They should do a drop test with the filler caps off so you can see into the cells.

They do a controlled short of the battery and see what current it provides. If the battery is shot there is usually gassing in the duff cell(s).

i went down to check the stereo fuze which was ok and i found the fuze which was another stereo fuze i had put to hard wire the fans had brittle plastic and limited to no connection through the fuse and cracked when i touched it this thick wire with a fuse goes to the possitive terminal i think ive found it. what do you think?

Don't count your chickens just yet.

Wait and see how it goes over the next few days.

I know it's easy to think you've found it, when you have really just talked yourself into it. I do at work often with avionic snags, you convince yourself it's one thing and nothing will sway you. Then after you spent ages trying to prove it, something else happens and off you go down another road.

Be patient for now, don't get a battery just yet.
