7264 starting

[lee434]

I have a 03 cub cadet 7264 with a Diahatsu diesel. turn ignition switch on-glow plugs work-park & oil light on-turn switch to start position-nothing. I jump across starter and starts right up. I would like help on what to check to solve problem. I would like info on how to check starter relay also.
thanks

Lee,

Welcome to TBN. Hope we can help.

First, make sure it's not something simple like a safety cutout switch. If it's hydrostatic, you may need to have the brake on, someone on the seat, and the PTO off. For a gear-shift machine, the shifter should be in neutral. Having accidentally left the PTO on is high on the list of possibilities.

To check the starter solenoid relay:

If your starter motor has one heavy gauge wire going to it, trace it backward to find the starter solenoid. It should have that wire attached to one lug, as well as another heavy gauge wire coming from the battery. There will also be a lighter gauge wire attached, coming from the ignition switch. With the key in the "start/crank" position, you should see 12V on that light gauge wire. If not, you have a bad connection in the wire, or possibly a bad ignition switch.

But if you do have 12V on that light wire, and 12V on the wire from the battery, but no voltage on the wire to the starter, then the solenoid is bad.

There is a very slim chance that the starter solenoid on your machine is built into the starter itself. In that case, both the light guage wire and the heavy gauge wires would be attached to lugs on the starter.

Lee, that is the same problem that i have been having for a long time. There has been several fixes posted in the past. From what i unsterstand the problem is that the total 12 volt volts from battery doesn't reach the starter.I will attach the fix with the parts number.

Thanks for your help. The relay is mounted away from starter so I can check that. I will also appreciate the fix with part numbers.

thanks again

Ted, I checked and no power to stater relay- I followed wire back to timer for glow plugs. I have power to timer, but no power out to orange and white wire that goes to starter relay. Would this be that the timer is bad or where else should I check.

thanks

lee,

I'm not familiar with your 7264, so I can only give you general information. I tried to find an electrical diagram for your Cub online with no success.

I'm pretty sure your glow plug timer energizes the glow plugs until either a given temperature is reached or a given time period has expired.

But I'm not sure about this: Does the timer prevent you from cranking the engine until that time period is up? or does it just display a light and you can crank the engine anytime you want?

Is there any chance this timing device also checks the other safety switches?

I would thoroughly check for a failed safety switch, bad connection, etc. before I'd condemn the timer.
