The manual/schematic does not coincide completely with what I see happening. From memory, I believe the glow plug timer/relay is located to the left of the engine as viewed while standing behind the machine. My glow plug light is on for about 5-8 seconds. But if I put a meter on the glow plug 12v power line, the plugs are powered up for about 12 seconds after the key is turned on. Sitting in the cab, I can see the voltmeter jump up slightly at the end of 12 seconds when the relay actually opens up. Having said all that, the dealer tells me the plugs get hot quickly, and going through several heat cycles in rapid succession will not make them any hotter, and will not make the engine start any better. You could pull out one of the glowplugs and connect it directly to 12v and see if it gets noticeable hotter after the first few seconds. On balance, seems to me if the rig is starting OK, the short glowplug cycle you see is probably OK. --- Bob</p></blockquote><p></p>
