154 won't start ....

Postby diogenes74 » Sat Feb 28, 2015 4:12 pm

I have a 69 cub lo boy 154...I am having problems starting...I am trying to start it from the solenoid, to find what is the true problem of why it won't start...the engine will start to turn over but will never actually run...does this mean the starter/battery is shot?

sounds like you have a fuel or spark problem. I just had to have my starter generator rebuilt a bearing went bad now its good as new

The fuel is on, and the plugs are sparking the real problem is that it won't turn over from the switch.. So I'm trying to jump from the solenoid to see if it's a starter generator problem or something else..any suggestions welcome...

Read this post several times.

Sounds like the problem is the solenoid or the ignition switch.

The battery ground cable is terminated to the tractor's sheet metal. Common corrosion problem area.

Suggest starting by cleaning up the battery cable ends and battery terminals - - - and then moving the battery ground cable end to the transmission.

I have moved the ground to a bolt mounted to the transmission and made sure I cleaned it up nice, I also just purchased a new starter and new wiring harness from Hamilton bob....double checked the schematic and still nothing ....

Here are three loose ends from a wiring harness I recently bought, it seems to run along the transmission housing , that have no connection points any ideas? The P/O clipped all the lights switches for front and rear, oil light, and I am pretty sure the safety switch as well..not sure where to go next on this 69 cub lo boy....

Those are connections for the clutch safety switch, the pto safety switch, and the rear light.
If you do not connect to the two safety switches, you must install a jumper wire between the two sides of these connectors, in order for the starter to operate.
The one for the light (yellow and white wire) is not jumpered, even if not connected to the rear light.

Thanks everyone for the insights....I will connect those loose wires and see if it will turn over, if not then it will be back to the drawing board....

Please excuse,my ignorance but I finally got her started but I had to do it at the solenoid. So I am assuming that the starter/ generator is working, it's grounded correctly, and the battery is good working order, but it still won't start when I turn the key.... I just replaced the the ignition switch as well as all the wiring, so once again I leave it up to the experts to solve my dilemma !!!! Thanks in advance

If you have power coming from the switch to the solenoid but no power coming OUT of the solenoid to the starter, then the solenoid must be bad.

Do you have a voltmeter or a 12 volt test light? Yo might try checking the orange wire at the clutch safety switch and see if you have battery voltage from there to ground when the key is turned to the start position. If not you probably have a problem between the battery and the ignition switch. If memory serves me the ignition switch picks up 12V at the side of the solenoid the battery is connected to. There should be a large wire from the battery and a smaller wire on that terminal of the solenoid.

If you have 12 volts at the orange wire when you turn the key see if you have 12 volts on the other wire with the clutch switch depressed. If you do you have a problem from the clutch switch to the solenoid. If your new harness has connections for both PTO and clutch safety switches did you jumper one or both if not used?

If you turn the key to the run position and jump the solenoid to crank the engine does it fire and run? If so you have 12 volts to the key switch.

Just thinking out loud here.

Larry B has hit on a couple of good points.
If you have the two safety switches connected to the wiring harness now, you must depress the clutch and be sure the pto is not engaged (the handle should be pushed down) in order to start
If this is not working, you most likely have a problem in the safety switches. I suggest you temporarily disconnect them and place a jumper wire across the connectors and try to start. If it starts, then you have a bad safety switch.
Using a voltmeter or test light can be a BIG help with finding the problem.
Keep at it and let us know every thing you do. We will find the solution for you.
