Question about 2002 Isuzu Trooper
I replaced the battery in January for my 2002 Isuzu Trooper. Did not drive it very much. Got in it it would not start or jump. took battery back to parts store....battery was bad...... replaced with new battery and still no life. Nothing no radio dome lights nothing how do I trouble shoot the main fuse and the ignition?
Check the fuseable link...4 looped wires in small (fuselike) box usually located at front of engine bay.check composure of four wires for break...replace if broken

In today vehicle there are many electronic device that still draw power from the battery.
Car radio memory on station pre-set
Car radio clock
Computer/ECU to save driving parameters
Car alarm + sensors
Power seat menory
To prevent problem,I will start the engine for 5 minutes once a week.
If are in an enclose area and has access to a power outlet then it's a good idea to connect a float battery charger to keep the battery is optimal condition.
Here is a sample of float charger / battery tender.
It's on sale for $7.99 now or you can but better quality one at your local auto part store for $30+

It's a good idea to check for worn belt and weak alternator.
A belt with 60,000 or 5 years should be replace.
Check the voltage at the battery terminal after the engine is warm up for 5 minutes. The voltage should be above 13.8V
Auto supply store may provide more in-depth battery and alternator testing for free.
Please email me if you have any question.
