Alternator tech inspection help needed
I suspect that the alternator on my FZJ80 is not doing its job well -- seems like I need to charge the battery using my trickle charger about once a month, and it's becoming more frequent. Questions:
1. How do I go about inspecting the alternator to find out if this is indeed the culprit of my problems?
2. I don't have a multimeter. Last time I was at Sears, the prices ranged from $10 to $200. What functions do I need on a regular basis? I prefer to buy good tools that will last a long time and be accurate, so if the $90 meter will perform more accurately and reliably than the $10 tool, I'd prefer to buy the good one. However, I don't want to spend $200!
3. If the alternator is the problem, can I rebuild it rather than replace it?
