amperage for starters

[Creekman]

Curiosity.

Not well. Many theories, but so far, I still don't have a presseure gaurge, so I am only providing partial data to get the proper help.

If you are curious about the amps required to start your TS254, you should buy an amp meter that connects between the battery post and the cable leading to the starter. They only cost about $125-$250, depending on the amp rating of the meter. To be safe, you should buy an amp meter with the largest rating you can get because the amp flow when starting a diesel engine measures in the hundreds of amps.
If you do this you can disregard all of the posts about "Ohm's Law" and get the amp reading you are so curious about.
I am beginning to smell old fish in your posts.

Actually Jeff has a 254, which is one size smaller than the 300 series. Not terribly important though, same size battery tray in both. I can't tell however - from your profile - if you even own a Chinese tractor, so you may not realize how physically large the OE battery is in the first place.

I replaced one of my JM254 batteries with an Interstate MT-49 (940CA/750CCA) made for Mercedes diesels. And I replaced one of my KAMA batteries with a MTP-93 (same case, higher output). Don't have a clue as to the Chinese battery amperage rating, but I seem to recall the 14"x7"x7" Interstates are physically a little smaller than OE.

But as large as the Jinma/KAMA/TaiShan battery compartments are, I don't think they'll quite accommodate a 20"x8"x8" 4DLT. Might get one in a Foton though. Their battery compartments are sized to accommodate a pair of pretty good sized 6v batteries. It's all a bit academic to me anyway, since the MTP-93 and 4DLT have the same basic 1000CA/850CCA rating anyway.

So I mis-typed.
What does all of this information have to do with the starting amperage of lakespirits KAMA 254?
I have a KAMA 354 and it has two 6 volt batteries in separate trays and are connected in series to produce 12 volts.

What's with the attitude? And since you already have a Chinese tractor (with two batteries in the compartment), it's now curious why you thought it necessary to ask " How big of a battery do you think lalespirit can cram into a KAMA TS354?? ".

I'm beginning to smell an agitator behind your posts.

[Yeah really.]
Shop around and you can get an AC/DC Clamp-on Ammeter with voltage function included for that price range. You just clamp the jaws of the meter aroung the wire and read the current.

I bought a set of these inductive ammeters (MT1009) quite some time ago for about 50 bucks and are capable of getting that reading your interested in.

I'll slip some shoes on and go see what my 790 draws.

Crank time was only about 2 seconds and it jumped around a bit, but it was definitely in the 300-350 range.

If so equipped, pull the fuel cutoff while cranking, and put the DMM on peak hold.

Ditto that... a decent clamp on meter with a peak hold would be a good choice for these large current situations.

It's not a DMM.

It's not a DMM.

There are plenty of dmm/dvm mm'S VOM's.. etc.. that have a clamp on function.. it don't matter it yours was a dvm or the little snap on job.. the advice is the same. the benefit of a peak reading hold is to see what it really gets up to, for comparison sake..e tc.
