What did the battery voltage check to be? Have yo checked the cable connections, at battery , negative to the frame and positive to the solenoid? Starter will do nothing in service or run position?

Battery cables are fine even tried to boost still won't turn over I'm kinda leaning towards the starter maybe but didn't think they would just go instantly like that
Mechanic: Curtis B., Technician replied 1 year ago

What was battery voltage or did you not check it with voltmeter? If battery has a bad cell, you can't jump through it.

Customer reply replied 1 year ago
Never checked voltage but battery is only a few months old
Mechanic: Curtis B., Technician replied 1 year ago

Before I went for starter, I would be checking battery!

Fully charged will be over 13 volts, and should have at least 12.5 volts to start.

I did put a battery charger on the other day and the battery was fully charged and it still wouldn't turn over but I didn't check the voltage just figured that the battery charger had worked
Mechanic: Curtis B., Technician replied 1 year ago

Battery may be fine, but voltage test will tell for sure. If it is 10 volts, it has a dead cell and you will not start! The seat belt and other safety switch lights show them to be working?

Yeah checked armrest and seat sensor seat sensor sometimes doesn't come on when you lift up with the arm down but may just be a little sticky

Even disconnected sensor on seat and put a jumper in but didn't make any difference
Mechanic: Curtis B., Technician replied 1 year ago

OK> So we are checking the battery?

Mechanic: Curtis B., Technician replied 1 year ago

Will engine spin if the battery terminal is jumped to the switch terminal on the same starter solenoid? If it does, battery, cables , solenoid and starter are ok.

Customer reply replied 1 year ago
We are checking the battery not sure if it will spin that way as I was trying to avoid jumping it that way

Customer reply replied 1 year ago
Battery reads 12.7 volts I can't try jumping it until tomorrow afternoon when I get back
Mechanic: Curtis B., Technician replied 1 year ago

It is not fully charged, but it may be enough to start engine. Only safetys are the seat belt and safety bar or seat switch.

Fuel solenoid is not opening the fuel as it is not getting good voltage. Is the charging system working?

Ask Your Own Construction and Road Equipment Question
Customer reply replied 1 year ago
No lights on when it's running
Mechanic: Curtis B., Technician replied 1 year ago

You replaced battery?Can you check battery voltage before crank, and after it is running? If charging, the voltage should increase at least one volt.

Ask Your Own Construction and Road Equipment Question
Customer reply replied 1 year ago
12.86 before starting and 14.3 when running never changed the battery as nothing wrong with this battery
Mechanic: Curtis B., Technician replied 1 year ago

Voltage is good and charging system is working. The fuel solenoid may be bad, and is not fully opening the fuel passage. It has to have battery voltage to work, do you get full battery voltage to it?

Ask Your Own Construction and Road Equipment Question
Customer reply replied 1 year ago
12.43
Mechanic: Curtis B., Technician replied 1 year ago

You can remove it and bench test it to be sure it opens fully, before replacing it.

Ask Your Own Construction and Road Equipment Question
Customer reply replied 1 year ago
I would think 12.43volts would be plenty to open it as with booster cables on you would be getting even more and why would that cause the machine not to start with the key?
Mechanic: Curtis B., Technician replied 1 year ago

Just because it has voltage it may not open. Solenoid may be bad. Think of it as a light bulb, and just because the switch is on, doesn't mean the bulb is good.

no movement, was there a plunger? I can't tell much from the picture. When you applied voltage , did it become a magnet? If not it does not work!
