Hello allI'll start by stating that I have been having a few electrical problems which makes it hard for me to really diagnose my problem so I hope someone can possibly help. I just installed new brushes in my alternator and had to solder a few loose internal wires. It is back in the bj and I am not sure if I did a good job as I was only able to test the vehicle for about 2 min before it cut off. The multimeter showed a slow increase in voltage from just below 13V to 13.01 V. Since then, my starter decided to go out. I opened it up to discover a wire that should of been connected to a contact was loosly fitted over the cover and wrapped around one of the cover screws to make a ground, I guess. The contacts looked like new and the brushes were in good shape. I was un-able to open the opposite side of the starter using the 3 phillips head screws so I left it at that and put it all back together. Now that it is in, when I crank the key the starter responds immediatley, I can hear the plunger hit the flywheel? but it does not spin the engine. I did not test the starter before putting it back in as I did not know how. Can someone let me know how to do a bench test? Does this problem sound like only a starter? I have used a battery charger to do a slow charge overnight and get the same results. The battery voltage averages 12.96V. This is a 12V BJ40 with one battery.thanks
