Combines 1660 Electrical problem

i have a service manual on the 1400 series with electric over hyd. ill look i might can even fax you a diagramIJ email me.

the ground for this circuitry is picked up at the cigarette lighter which could be a problem or it could be the oil pressure switch on back of engine . the one that has 2 wires on top of it. what i do on the cig. lighter circuit is find the wire that grounds the lighter and splice a wire direct to chassis. or can be broken wire in this loop.

the ground for this circuitry is picked up at the cigarette lighter,find this wire and jump it to chassis. also can be oil pressure switch on back of engine. the one that has 2 wires attached. put jumper on the 2 terminals to see if you have bad switch. or can be broken wire also.

Make sure the engine revs are displaying ok if not replace the sensor.But I think it will be the oil pressure switch on the engine There are two on the side of the block. One is for the guage the other is a safety switch so that the hydraulics cannot lower the front when the engine is not running

Check for mouse damage under the operator seat.
