Traced it to the alternator. When I disconnect power from the alternator, negative batt terminal to chassis reads 0V. Connect the alternator, and that voltage spikes to like 10V and then quickly decreases to about 3-4V. So it seems the Alternator is shorting to ground, right? this is with all other wires to the alternator disconnected. Is there a way to track down where the short is inside the alternator, or should I just replace it? The machine will run, but I'm not sure if the battery is charging while it's running other thing is that I was getting a slow voltage leak from the glow plugs. The glow plugs were off, but voltage between the two battery terminals would slowly drop from 12 to 10V over about a minute. It stopped draining when I disconnected the glow plug wire, so I figured the glow plugs were shorting somewhere. Is this fix to remove and replace all the glow plugs or is there a way to troubleshoot it? Can I do that without removing the engine? thanks</blockquote>
