Had the jensen running...now won't start. I charged the battery up so it is fully charged but when I turn it over it seems like the batttery is almost dead as it turns over really slowly and of course does not start.

 

Is it possible that the battery might be done even though my charger says it is fully charged??

Could it be another reason why it turns over very slowly?

 

Thanks!

Start by getting your battery checked. If that's not the reason then it's time to start checking wiring. :)

I assume that the battery was good the last time you started the engine, and you removed it to charge it for some reason.

Perhaps there is a loose or poor connection in the battery / starter circuit, or a bad / broken wire.

Remove the battery terminals and posts & clean them up with some 400 grit paper. Some dielectric grease won't do any harm here. Do the same to the earth lead to the body & check/clean up the starter terminals. When a battery goes bad it won't hold much of a charge and the acid becomes as much use as water. Even if it is the battery it won't break the bank.

It could also be the starter. Has it ever been changed / updated?

Standard no start procedure (on a car that previously started):

1) take battery to autozone for a full charge and test. (takes ~1 hour to charge)

2) While waiting clean the terminals/connections for the Battery, alternator & starter.

3) While you're in there check for broken/melted/frayed wiring.

4) Take the time to clean the ground straps and the negative terminal connection to the body *really well*

5) Remove the alternator, go back to autozone.

6) Test the battery & Alternator. If both pass, reassemble the car.

7) If the car won't start (and the starter doesn't sound strong) remove it and get it tested.

8) If starter passes, then the problem's in the wiring. Get out your volt meter and start doing voltage drop tests. Look speciically for voltage drops of >.2

Thanks...I'm going down that list. I managed to get a new battery...I did look at the alternator today and the connections seem to go back to the solenoid. I have to take all the tape off the wires and see exactly where they go and obviously clean off the connections.

Well if you have a new battery and it is fully charged, does the engine now turn over faster. I dont think you have a starter issue or it would not turn the engine over at all. As mentioned you could have a alternator problem if the new battery keeps losing charge, what does the gauge show your charge rate at.

The real biggy for most electrical problems are as stated, dirty and bad connections.

Ok put the NEW battery in and turned it over...same deal...it turns over slowly like it has low charge but it's brand new.

I want to confirm that if the starter was faulty it wouldn't turn over at all??

Also, if the alternator was faulty it wouldn't stop the engine starting if the battery was brand new, right??

I'm going through all the wiring but want to understand why the engine would suddenly turn over slowly suddenly like this?

To answer your questions:

1) Starter can still try to work (e.g. weak starter) but still be failed.

2) Correct, with a good battery you should be able to start with a bad alternator.

Go back to my earlier post and refer to the steps to follow.

Is the new battery fully charged, it could have been sitting on the shelf for a while, try giving the battery a jump start, does that make it turn over faster

How much power are you getting to the starter when cranking ..... have you cleaned up your wiring connections plus the grounds .....

Does it turn over at the same rate with the car in neutral,  or faster with the clutch depressed.
