Engine Fuel pump died after battery failure

[reynoldston]

It seem like a lot of problems for just a dead battery?? A dead battery shouldn't do any damage. Did you hook up your jumper cables or battery up backwards? Or were you running the mower and it died and then the battery was also dead ? Are we missing part of the story here.

Here is the sequence of events:
Cut for about 3 hrs.
Shut down and greased spindles and general mower clean up for about 10 min.
Went to restart. Solenoid clicking but did not crank. Put charger on for 30min.
Took no charge whatsoever. Tried to start. solenoid click only.
used an automotive battery and cables and it started immediately
Ran the mower for a min and then Engaged PTO and it promptly quit.
Jump started again to get unit back to the barn. It ran a couple hundred yards with a couple of momentary hesitations and then completely quit. Put the jumper battery back on but it would not restart. Noticed no fuel pump activation when turning the key to on.

New battery: Cranks strong. No fuel pump activation. No ignition spark.
Fuel pump does activate when jumped.
All relays and fuses check OK.

Will check ignition switch tomorrow.
Pulled seat safety delay module but did not know how to check. will probably just get new one.
All safety switches seem to be working normally.

pull off the engine cover.
Sounds like your mower may have become the Rodent Hilton.
Or the mower is not charging or both.
Spark has nothing to do with the battery unless you have one of those fancy computer conrolled ignition modules.

You will need to go to Hustler and download the circuit diagram and also post the full engine numbers if you want any more help.
You are about the end of the generic information road so we will need to check information before posting any more replies.

If the starter solenoid clicks then you are getting power to the ignition switch and the safeties are most likley working.
There might be more than one fuse.
The no crank safety switches usually work on the solenoid + side and are a daisy chain .
If you have a 4 pole solenoid then they work on both the + & - triggers, the latter stops you accidentally engaging the starter with the engine running.
Every thing that kills the engine generally earths out the magneto coil and are all wired in parallel singularly or in a chain ( blades + seat or brake + motion control )

Yes, It is one of those computer controlled units with fuel injection. Iwas reading last night on how to pull the codes on the ECM. Ido not believe there is a rodent problem but it can't hurt to look. It is almost time to send to the shop to diagnose but I will still give it some time.

Will keep you informed. Again thank all for the great information and your time to reply.

I can't accept defeat!
