Battery or Alternator problem

Finbar1972 · 19th March 2019, 16:10

Hello

I am after a bit of help, please.
I have a 53 Reg 75 2.0 Cdt and recently the battery has started running flat. I put the battery on charge until full and it runs great (1st turn of the key) and then it all of a sudden when I stop the car it will not start again and the EP light comes on the dashboard.

Not sure if it is the battery or the alternator.

Any ideas?

Sounds like the battery, how old is it ?

Do you have a test meter to test voltage? If you do, what voltage are you getting across the battery terminals? With the car running what do you get across the battery terminals?
If you don't have a tester, fully charge the battery off the car, then disconnect the battery and leave it for a few days, then try connecting it back to the car and see how it starts.

You should, with a voltmeter, get 12.5 to 12.7 volts at rest and over 14.00 volts with engine running
