SOURCE: I have a 2006 Cub Cadet RZT 42 Zero Turn Mower

you have a wire that is grounding out, I would check the wire coming from the connector on the voltage regulator to the battery. This is the one in the middle position, look for a rub through and tape it up.

Hi and welcome to FixYa, I am Kelly
The service manual is here:

The wiring diagram is on page 84 of the manual.

Disconnect the positive and negative terminals from the battery and make sure they do not contact the chassis to form a ground. Read for a short with the key in run and lights OFF from the positive battery terminal to chassis ground. If you ar noting a short at this time you are literally going to have to chase wires. I would start by disconnecting the red wire from the PTO switch followed bythe red wire on the PTO relay. If the short goes away I suspect a problem with the wires at the PTO clutch as this is were many wiring problem manifest due to foreign objects thrown by the belt hit the wires on the clutch. After that I disconnect the engine connector and check again. Lastly I would disconnect the dash monitor connector and test again. If you still have the problem after disconnecting the engine harness and dash monitor there is a wire chaffing some where against the chassis. You can find it... it just takes a lot of time.

On another note...
You should probably make sure the ignition switch is not causing your problem.
Key switch testing connector removed
Off = M+G+A1 (continuity) Also read each one to the case of the switch
Run W/lights = B+A1+A2 and L (continuity) Read B + A2 to to the case of the switch.
RUN = B+A1 (continuity)
Start = B+S+A1 Read S to the case of the switch. (continuity)

Don't forget to remove the large (+) wire off of the start solenoid when troubleshooting or you will read the starter winding giving you a false ground.

Troubleshooting will end up being isloation of one leg of each wire at a time. I usually make a straight line sketch of wire temination points by wire color and connection on scratch paper for each wire I test and draw a single angle line across it after I have tested it.

If you determine that the problem is in the engine alternator, I will need your engine model number so I can get the service manual for that also.

A word to the wise.... if you disconnect a wire... write down color and where it was disconnected from on scratch paper. and line it out after you re-connect it. (experience)

Thanks for choosing FixYa,

Need to know how to change transmission fluid on cub cadet lt 1045 riding mower

Cub Cadet has five models in their new Series 1000 lawn tractors, all powered by Kohler engines. Cub Cadet models -- as several other lawn equipment brands -- are manufactured by MTD Products.

The Cub Cadet LT 1045 has a 20-hp Kohler single-cylinder engine, with an aluminum block and cast-iron sleeve for longer life. It has a full-pressure lubrication system with spin-on oil filter for easier maintenance. This engine is not as powerful or as long lasting as the Kohler V-Twin OHV, which is available in other models in the line, but the LT 1045's engine is still solid enough to provide years of mowing.

The hydrostatic (automatic) transmission is a good match with the engine and provides sufficient grip to cut grass on moderate inclines. Power is transferred from the engine to the transmission by a heavy-duty Kevlar belt rather than a more expensive shaft drive. A Kevlar belt also drives the three cutting blades.

The mowing deck cuts a swath of grass 46 inches wide at one pass, and is removable for service and cleaning. Four anti-scalping wheels help keep the deck from scalping grass on uneven ground. The cutting height is manually adjusted from 1-1/2 to 4 inches. The turning radius is 18 inches, which standard for lawn tractors. This model is intended for use on 1- to 2-acre lawns without many turns or small obstacles.

Cub Cadet LT 1045 - Not starting, the engine does not turn.

I have a cub cadet LT 1045 and every so often the blades will stop cutting even though it remains in the engaged position.

There are a few possibillites: a bearing is starting to go on the quill assembly or idler pulley; the PTO on the engine is heating up and quitting to work until it cools off; or you may have a switch going bad. I would look at this first.
Good Day

Cub cadet dead as a door nail

I have the same mower. The wires do need to be connected. It is a safety feature on the cubs. The engine will not start if the electric PTO is engaged. I just went into the garage, pulled the pto lever out to engage, pushed down brake, tried to start and it would not start. I suggest reattatching the wires and trying it. Hope this helps.
