Well, I’m just about to pull the trigger and buy a new bumper for the Jeep, and this past Friday I go out into the torrential downpour only to find the Jeep is dead. Completely dead. No dash lights, no odometer, nothing.
Over the weekend, I pulled the battery (a Northstar ultra high performance one that I purchased a year or so ago from Battery World – read -“not cheap!”) and hooked it up to a charger, and after a few hours, the charger displayed “bad”.  Tested with a multimeter and something discharged the battery down to nothing – but no idea what.
Hopefully can get the battery replaced and all will be good in the world again!  If that doesn’t fix it – then I’m afraid my bumper budget will get swallowed up in troubleshooting and fixing an electrical problem!
Update:
Things are looking promising I think – Battery World has the battery now and are testing it, and recharging it.  In the meantime, they gave me an Optima Red Top to throw in the Jeep and see how things go.  With the Optima, the Jeep fired up – which is encouraging.  I ran the Jeep a little while – checked the voltage while running – which came out to 13.8 volts – which I think is in the right neighbourhood.  Tried this morning, and the Jeep fired up again as well.  Fingers crossed – hopefully Battery World calls back soon!
