    Hi Guys,
    Got a wee bit of a problem. A hacked up electrical system. Really need a schematic to sort it out in the time-frame I've been asked to do it in.

    Here's the tag:

    If anyone can help with a schematic, I'd sure appreciate it.

    Mainly cannot activate the vibrator motor, but there are no safety devices in use. No seat belt switch, no "neutral start" switch (will crank and take off), no back up beeper, and who knows what else. Lots of loose, some hot, wires in the thankfully plastic console. Some of the instruments have been replaced with aftermarket/generic gauges which probably caused some rewiring that left unused wires loose. The control for the vibrator speed is incorrect. The pot that sweeps the speed has both outer ends tied together so that the wiper can only read a single value. It's the 1k pot under the main knob. Judging by the soldering job, obviously not factory. At least the majority of the wire markers are still there, except for the added wires spliced in. Color and wire gauge changes at splice points. Key switch subbed in rather than push-button.

    The machine will start and run normally, so no engine related problems, but not so sure about the pump/vibe motor circuit. Solenoid clicks with power applied, but don't know if it is actually opening. Have a flow meter on order but it will be slow getting here. At this point, can't get it to vibrate, but it could be the amplitude/frequency controls for all I know.

    I had the same problem with my sd25 and finally found that there was a rub short in the wiring from the vibrate/ forward reverse console

    murfdog, presently, I have that console all opened up and spread out. I found no accidental damage anywhere, just butchery. I've got the schematic now, so it's game on trying to put back what I can with what's left of the controls. If I can just get everyone to leave me alone with it, I can get it functional, provided there isn't a mechanical problem with the pump or vibe motor. As always, time is not on my side. The machine, actually one of two (other one is a Hamm, German mfg packer) that is in about the same shape electrically, but AFAIK, it doesn't have hydraulic problems. The turbo was ready to explode, and pumping about a pint a minute out the exhaust. New turbo arrived yesterday but wrong gasket and stud kit. The dash is all apart, so it might have some electrical issues but I haven't looked it yet. Someone else is on that one. Maybe we can get one out of two rushed out.

    Anyone see anything wrong with this pic?

    Apparently the schematic I have (in the op/maint manual) is incorrect for this serial number. It states that it starts at a sn significantly than my machine. They made quite a few changes so this schematic is pretty much useless. Oh well....on with the hunt.
