Have an '81 Miller Wildcat 350D with the Waukesha VRD155 4cyl diesel. It has the 1800RPM Roosa Master IP. Model 3245170 (seems it's that # or the following) C-207634-C. It's 12 volt.
Was redoing the tailgate on my dump truck, went to start up the welder but no go. Not even a faint puff out the stack. There's fuel and power going TO the pump but that's it. Even changed the wire to the other terminal on the IP with no change.
The rig is used sporadically...but during the last half dozen or so times when it came time to shut down...the solenoid has clearly been sticking since even with power cut off to the solenoid it would stay running though roughly since the solenoid was turning off maybe half-way. Would have to tap on the top of the IP before it would finally shut down.
Since 95% of the time when using the welder the panel is always within arms reach...had to bypass the defective Murphy Switch and had rigged the solenoid directly. Had installed a 12V ballast resistor in-line with the toggle switch and solenoid since it was clear after the 1st time that direct 12V was TOO MUCH since it would stick...hard. With the resistor in place it engaged smoothly. This setup was done a few years ago and has ran without incident until the previously mentioned...
Since I would have to pull the top of the IP regardless...does this appear to be the right one? http://www.ebay.com/itm/171755384961?item=171755384961&viewitem=&vxp=mtr
