Bad charger?

A typical 6v battery has around 200AH of capacity, so if your charger puts out 20 amps and the batteries were totally discharged, it would take over 10 hours to charge.

Since You have a timer, hopefully You have a ferro resonant type charger with the big capacitor inside.

Does the charger have a working amp meter that you can verify it is starting the charge at a high rate (max output) and dropping as the battery charges?

Yes, it does have an ammeter. It shows right at 20 amps when I first plug,it in. Then, it slowly comea down as it charges.

That is good, just monitor the meter and make sure it stays in the under 5 amps range for at least 1 hour (typically 1-6 hours in that final phase) before the timer goes off.

Problem solved. I found that the ground coming from the receptacle had a loose connection and was causing heat (resistance) in the wire. I replaced it and the Positive wire , plugged it in and all is well. Thanks
