Thread: Battery Jump Starter Pack for N70ZZ Battery

Hello All,

I took the battery to an independent battery place and they tested the N70ZZ battery under load. The 720 CCA battery was putting out 340 cca. I have had the Battery Fighter hooked up to it since my last post and the light was fixed green. All fully charged when I took it for its test. I have walked out the store with a new battery - not one of made by the crew who produced the battery I got tested. Next in line for replacement is the Battery Fighter.

I just got back from town so I will install the new earth lead and see if the tractor makes vroom vroom sounds. Fingers crossed that it was just the battery after all.

Kind Regards
Lionel

Hello All,

Do new batteries come fully charged?

Should a new battery need charging after less than four hours of operation in a tractor?

I had to move the cable a bit before the tractor could start - like a sweet spot where it prefers being . I had moved it a bit earlier after I tightened it up. There were loud clicks to the solenoid - unlike before with the older battery - that produced no sound at all.

After about after three hours of operation the damn thing stalled in the creek crossing on the nature strip and then totally refused to start again.

The tractor had to be towed out back into my paddock courtesy of the next door neighbour's Japanese four wheel drive. My only operational Series III has an issue with selecting four wheel drive so despite a valiant attempt in two wheel drive I had to concede the point - swallow my pride and get a tow.

I am going to get an auto electrician in to check to see if the generator or alternator is charging properly. Or to see if something is drawing current out of the system.

The new battery has been on charge for a couple of hours now.

I have just returned with a SJS Smart Jump Starters Pty Ltd Smart Jump Start Charger Generation 2 for up to 4500cc diesel and 7000cc petrol engines. SJS06G2 Smart Jump Start Charger 600A

At least next time I may be able to jump start a flat battery. Now to find a mobile auto sparky.

Kind Regards
Lionel

It sounds like a new solenoid may be in order, Lionel.

Hello Ian,

I will see what the auto electrician says first. So far I have spent over $400 in battery related stuff today. Therefore, the cost of an auto electrician getting to the bottom of the issue is going to be value for money. Also, being able to just turn a key and then go out and mow or pull stuff around with the tractor.... when I want to will be worth it.

The Jump Starter is fully charged now. The new battery is going to be left charging over night. Tomorrow I might be able to actually finish mowing the paddock. Just got to the other side of the creek and the job is done. Main paddock and nature strip tamed - just the section of paddock across the water, dubbed Van Diemen's Land to go!

Next RDO there will be an auto electrician coming here to sort the tractor out.

Kind Regards
Lionel

Hello All,

I fully charged the new battery and installed it in the tractor. No click of the solenoid. I pulled the covers back from the wires on the starter solenoid and I noticed that the insulation has bubbled up and melted on the positive and earth wire. The is now more movement in the plastic disk face where the two terminal posts are secured to.

A new solenoid is $48.00 USD so I am about to order one + freight. My tractor is considered a Grey Import and the local Yanmar dealers are not that friendly towards my tractor. They are missing out on business however that is the way they like to play.

Does anyone know of a Yanmar dealer here in Australia who is not so anti-grey market tractors? Otherwise I will go down the route of two American based suppliers I know of.

Kind Regards
Lionel

I would take the solenoid to a nearby auto electrician and see if they can supply you with another.

Lionel, I used to own a (12V) truck that that regularly lunched solenoids, I fixed it by installing a 24V solenoid. Try your local sparky, he can give you the best advice and supply over the counter, probably cheaper.

Hello All,

Just an update - the starter solenoid arrived from the good ol' US of A last week. I got some time this weekend to fit it.

I turned the key to the left to get the glow-plugs warmed up ... turned the key to right and the motor fired up straight away!



Before going down the overseas supply route I was cited lots of interesting information about "Grey Market Tractors" no authorised agent allowed to supply parts to vehicles not imported to Australia. Also, that I would have to buy a complete starter motor as starter solenoids are not sold separately.

So I went to overseas suppliers armed with measurements and photographs of where the starter solenoid engages with a lever that brings the stater motor gear forward. It turns out that there are three separate types of arrangement where the starter motor engages the lever. Plus one of these has six or four Millimetre diameter bolts to secure the solenoid.

After a couple of emails between myself and Hoye Tractor Parts from Texas I had the stater solenoid delivered to my door. A special thanks goes out to Aaron from Hoye's.

I deliberately drove through creek where it was towed out a month or so ago by my next door neighbour's four wheel drive. Then I proceeded to mow the other side of the creek and tamed the long grass.

After all this was done I cleaned the tractor and drove it back to its shed.

Kind Regards
Lionel
