Jinma starting

[guitarman]

Have a 2005 454 Jinma runs great but some sometimes have to bump key several times to start sometimes nothing but will always start if I jump it at starter. Previous owner eliminated clutch safety switch so that's not it. Thinking it's a problem with switch.

Clean earthwire and spray stopcorrotion and see if that helps ?

Completely cleaned all cable connections and made sure battery was fully charged still had problem that's why I think it's switch, anyone else have similar problem

Could be the switch. It could also be the 30A fuse that feeds the switch, I find sometimes I have to pull it out and push it back in again to get it to start.

Could be the switch, high resistance connection(s), or bad solenoid on starting systems I am familiar with.
On my ZD mowers I wired a relay at the solenoid to ensure adequate voltage to the solenoid when I was having similar intermittent starting problems, which fixed my issue. It’s a pretty common wiring upgrade. Google “starter relay wiring” if you decide to try it.
Best of luck!

I had a Jinma 204 I think it was. Ignition switch went south as i was constantly hitting it with my leg. I replaced it with one I had off an International tuck and put in a separate push button and indicator for the glow plugs,...............Mike

Ok battery fully charged clutch safety switch not an issue everything hooked back up and it started, shut off tried again, nothing shorted at starter and it starts right up every time. if I kind of "wiggle" the key in the switch as i'm turning it then it will sometimes start. so first my original Chinese battery from 2005 is finally with a little over 300 hrs getting tired, second the switch is not always making good contact inside to start. So will eventually replace switch for now will use remote starter button when switch doesn't work.

Or you could call Affordable Tractors in Texas and get a replacement for probably el-cheapO. lol Order on a Monday and have it hand by Friday is usually how it goes when I've gotten parts from them. Very reasonable.

Invest some time in reading and then doing the fault finding in this DENSO publication.

It will zero you in on the problem and avoid wasteful parts changing.

used tractor for loading trash into truck on saturday started fine three or four times then nothing shorted across leads at starter fired right up. always starts easy first turn and will always start even when I have to do it at starter. made this post when tractor had sat for little over a month when we were getting rain. and starter would not even spin which turned out to be battery is finally getting tired so first order of business is new heavy duty battery then will replace starter switch. Has been a good tractor only other problem was caused by some loose bolts which cause the mount for the right lift arm to break out of housing. had to drill out and put thread inserts in, put lock tight on everything and check all bolts more often.
