Kobota ZG327 no start

[samcarpen]

Kubota ZG327 Commercial Zero-turn with 27hp Kubota engine no start. Cranks. Will temporarily fire when misting fuel into air-cleaner. Blows 15amp main system fuse. Disconnected fuel pump and continues to blow fuse. Can't locate a wiring diagram. Parts dealer who is also a Kubota dealer is very little help. Suggestions would be appreciated. Thanks, Sam

If is blowig as you switch to run then you obivious have a short but as how this is setup I don't a clue as I haven't seen one in the shop yet. But I would tried disconnecting the afterfire solenoid on the carburetor to see if that stops the fuse blowing. These do short out. If shorted then replacement is needed for the engine to run.

The service manual should have a copy of the wiring diagram in it. Available for the ZG 327 ZTR from https://www.tradebit.com/filedetail.php/278681534-kubota-zg327-zero-turn-mower-service-manual

Thanks for your help. Was able to obtain a wiring diagram. Turned out that it was the fuel pump relay that was shorting out.
