17.5 Intek Head scratcher!!

[Michael72]

Howdy folks

Having one of those days!!... have a John Deere with a 17.5 on board with some minor jobs needed, now .....

Mower sounded a little rough and hard to turn over so I went to valves and adjusted as battery was given me a healthy reading.

It is still hard to turn over so I go to solenoid with power coming in at 12v ish, Out reading to starter only gives me a reading of 4/5...when powered on bench the solenoid has continuity with click ...

Never had a solenoid go weak always just go completely.....is it possible???.....any advise much appreciated:confused3:

Edit : If I jump the mower it will fire up and will continue do so while in use....but leave for an hour or so it wont....also I checked battery when running and its at 13.3 ish so charging i guess...if I cross terminals on solenoid it still wont turn starter enough.

That's certainly a head scratcher, I'd start with a check and make sure that all your electric connections are clean and properly attached.
Last time I had that happen it turned out to be a fuse in line with the alternator at fault. Once I replaced it then everything was fine.
Do post some pictures so we can see your machine.

Seriously consider having the battery load tested.

Cheers will do.....I think under 9.5 is a fail under starting load?

Long shot try reisitance check of solenoid, if poss, with solenoid switch engaged without power. (imposs?), or voltage drop accross solenoid when switched. Should be low if any ohm and ? .500mV- 1 V drop? I'm winging it. Switches can become corroded , worn of cladding, etc. Substitute solenoid (without buying it).:2cents:
