On a short drive home the other day my volt meter dropped to 0 and the "check guages" light came on. When I opened the hood I noticed some fluid on top of the passenger side battery and a slight hissing noise. Reading the manual I thought there might be a over charging issue. The next day I drove the truck about 10 miles. The volt meter read on the low side of normal for a few miles then dropped to 0 again. When I opened the hood after the 10 mile trip, I saw the sight glass in the passenger side battery blew right out of the battery and there was spray all over the engine compartment. I replaced both batteries that day, thinking this was going to slove the roblem. The next day driving to work the volt meter again read low and dropped to zero after a few miles. I disconnected the negative lead from the passenger battery and now the volt meter reads fine. I'm wondering if I have a faulty voltage regulator. If so, my manual says its an intergral part of the ECM. I did a search but couldn't find a post of a similar issue. Can anyone give me a place to look to diagnois this and has anyone else had a similar experience? The truck has 94k the the batteries were original. Thanks in advance.
