I went to start the 4110 tonight and it was very close to not starting. I was out in the barn long enough to draw a crowd:lol:. So, I think the combination of an old battery (still original) and 8 degree weather was the issue. My 2 buddies think its the glow plugs. So we have a bet.

Other than pulling them out, how can I prove electronically that they work.

Thanks! :good2:

Testing can be done in the engine...but you have to remove the wire from the GP-it's a threaded stub with a small (maybe 8mm) nut on it. Once the wire is removed, take your Ohm meter and place one lead on a good ground, and the other lead on the threaded stud (make sure you have a good contact-they are painted), the meter should read near zero resistance, or almost a dead short (like if you touched the two leads together) if the GP is good. No reading indicates a open GP.

Remember that the GP's only fire while the starter is cranking-there is no pre-heat circuit, so a weak battery will not get it started easily when it's cold out. My method is to pull the PTO switch up or place in gear for 8-10 seconds to allow the GP's to pre-heat the cylinders before actually cranking the engine.

Really? That seems like an odd setup... I'm no electrical guru, but wouldnt it be slick to use the key switch from a 3x series so you could wire the gp's on its own circuit for cold starting....

Dave, believe it or not, thats how the 4110 is. Its in the manual.

Thanks Kenny. I have to think its the battery, but we will run the test and I hope to win the bet.:munch:

Yup, that is the way they work...same on the 2305, 2320 and some of the early 2520's. I guess it was cheaper that way:thumbsdown: The 3x series switch would be nice-but probably not worth the effort. This system is quite workable once you understand how it works.

I believe you guys 100%...I just think its an odd setup, machines prior and machines after had/have glow circuits....On a cold day like today I dunno how that would pan out for me here..LOL.

That's why I wrote this tip:

I do not believe the 2520 ever had glow plugs, just like their predecessors the 4115, always been direct injection....

Just as a follow up.

Testing went perfect. GP's are good:thumbup1gif:

Battery, not so good:morning2:

I won the bet, but have to pay for a battery.
