I have a 15.5 hp riding mower, I shut it off the other day to put oil in it, and when I tried to restart it no voltage, new battery, 1 month ago, I have voltage to the solenoid, and to the fuse, and one hot to the ignition switch, no lights, Give me some good advice to try to get it to running the grass here grows at night.

Thanks Richard

Save yourself some agony and follow the directions do not skip one because "you have already done it" humor me and you will see the light.

You will need a volt meter and set it to DC volts
-Check the battery for 12.5 Volts
-Check the cables attached to the battery for the same voltage checking for good connections
-Attach the positive side of the volt meter to the + side of the battery and the negative side to the engine block, Still got 12 Volts? If not the ground from battery is bad.

-Now keep the ground on the negative side of battery
-follow positive cable to the solenoid and hook volt meter on the cable going TO the starter coming from the opposite side of the solenoid.
Turn key to "start" position you should have 12 + volts

YES-Check the same way on the starter motor where the cable FROM solenoid connects, If less or no voltage then cables or connections bad, If good voltage then starter is bad

NO- Take positive lead from volt meter to small wire going to solenoid and test for 12 Volts with key in the "start" position, If no voltage to small wire safety switch is telling it not to crank or ignition switch is bad (rare) If it does have voltage the solenoid needs replacing (common)

Hope it helps,
