battery light is on gauge shows that everything is working as it should.. got out my volt meter and battery shows 12.8 with truck off and 14.78 with truck running at idle which is within specs for my 93 ranger with 2.3L... after a little more research i found that the idiot light uses a separate wire plugged in to the alternator, on my 93 this is a white wire with black stripe and from what i have read the connector within the plug will corrode and break.... have not been able to repair yet as it is a pain in the back side to get to this connection.. but wanted to let everyone that finds this post know it is best to check your alternator output first before spending the money to replace as it me not be the alternator that is bad..
