2000 JCB 214e series 4 Won't start

Mrclean1985 · Dec 2, 2020

Couldn't really find any threads that were particular to my situation. Cranks but very slow. What I have done so far. Drained old fuel and replaced with fresh fuel. Replaced fuel filter and bled air. Replaced battery and starter. Replaced battery cable ends. Still cranks slow. Use to be able to jump it to get it started but that doesn't even work now. Any other areas I could check? My next idea was to replace both battery cables. Something is drawing the battery from 12.8v to 9.8 when you turn the key. Any help would be appreciated.
Thanks

I'd check the other ends of the battery cables. Try putting jumper cables directly on the starter to see if that makes a difference. Then that will show you have a wiring issue.

Does yours have a batt isolator if so link it out ,also check earth lead on engine block and make sure no hydraulics are loading up on cranking

Totally thought this was the problem. These are the wires coming out of the little 5 fuse box that connects to the positive terminal of the battery. Replaced all the fuses in that box too. Unfortunately it made little change to cranking. Also checked and cleaned all the grounds today with little return for my efforts. Did get it to run finally but it's really hard to start and takes a lot of cranks. Volts still dropping from 12.8 to 9.8v when cranking

Do you have jumper cables? Connect from your battery to the starter. If that don't make a cranking difference, connect from other vehicle, and to the battery. See how it cranks. Then connect to the starter. You need to rule out the wiring is bad or not. Then rule out the battery, and ultimately the starter.

Yes, I have a commercial charger that has a jump feature. I hooked up the jumper cables to the starter and made no cranking difference.

Jump feature charges the battery. It doesn't act like a battery. You're doing it wrong.

Did you replace the starter as some starters are better than others ,has this got a RJ build perkins engine in.
If you have the perkins RJ there is a glow plug relay box in the engine bay which could be an issue just depends on engine have you a serial number?

What voltage you got at the solenoid wire to starter ,try triggering starter from the battery pos on the starter with a jump wire and see if that changes anything.

Oh sorry. I thought the jump feature was like jumping starting from a vehicle. I will first try taking jumper cables from its own battery and connect to the starter. Then I will connect from another vehicle to the jcb battery and see what happens. Then connect to the starter and see. I'll report what I find.

I have a rebuilt AIS starter for it. Serial number is AR50656U009934D

The trigger wire for the starter solenoid so the smaller wire at the starter.
Pull the that wire from solenoid and give the terminal that you removed the wire from 12 volts from the the machine battery and see if that makes a difference as you are by passing every thing up stream of the starter.
Was this fault the same with old starter as well as new starter any improvement.
Other thing to check as i said before is to make sure that hyd circuit is not loading up ,perhaps try using the crowd dump lever whilst trying to start.

Mrclean1985 · Dec 4, 2020

So I noticed the one of the grounds on the starter getting really hot when cranking in a short amount of time. This cluster was connected to the negative terminal on the starter. I disconnected and the starter wasn't getting as hot and the volts were only dropping to 10.6v now and not 9.8v. Any idea where this cluster is suppose to connect to?

I tried what you said with little wire from the starter with no change in cranking speed. Sorry for the dumb question but what is the crowd dump lever?

Mrclean1985 · Dec 4, 2020

Also this thing has been cobbled by many different mechanics before me. Can anyone tell me what the correct battery is for this piece of equipment? I just want to make sure the mechanic before me put the correct one in.
Thanks

I think it should be around 1000cca. You can pick up at farm stores.

Those yellow wires were connected to that ground stud out the back of the starter? I know nothing about JBC, but it's British? I've never seen any Brit vehicle with anything but black for grounds.
Is that a rebuilt starter on there? Lucas? Is that the rebuilt you said you had, not clear if you have one or you installed one.

Yes! That cluster was connected to the negative terminal on the starter. I know that is not where they go but have no idea where they should go. The starter is a rebuilt that I purchased from AIS and they said it's an OEM starter. I don't know if it's a lucas. I will have to look on Monday when I return to work.

Those wires bolt to the stud on the end of the starter i believe. They can probably bolt to any ground.
And you can buy new starters for $100 on ebay. You can find many common jcb parts on ebay.

Mrclean1985 · Dec 4, 2020

Ok so here is an update guys. Those wires connected to the negative terminal on the starter was smoking the other ground on the starter. Turning then it red hot. After disconnecting them voltage drop at the battery when cranking was going down to only 11.0v instead of 9.8v. Still can't get it to start just off the battery alone but now I only have to put the battery on the charger on it for a few minutes and it was firing right up today. I'm thinking I need a better battery. I was thinking this one. Any thoughts?

joe--h · Dec 4, 2020

Are those yellow wires hot when the key is on? Hot in the crank position only? Never hot?
You don't have a wiring diagram I guess?
