If it was an antique tractor I wouldn't be having this issue!-

NH TT60A starts fine all summer, but not in cold weather. I think I've found that the annoying alarm is draining the battery.

The issue I have now is my multimeter. GB, GDT-11. I've used this inexpensive unit for years. I have never tried to use the DC 10 amp tap until now. Instructions claim this circuit is not fused. Yet trying to use it immediately blew the little 200 milliamp fuse?????

Why is the alarm draining the battery? you are talking about the alarm that bleeps when you get out of the seat without setting the park brake or taking it out of gear?

Can you elaborate more about the problem?

On my little HF $4.95 el cheapo, there is a 10A function on the dial and a highlighted area taking you over to the 3rd port just above where the red lead usually sits. Red lead goes here for 10A function.

Yes, it's that annoying alarm. I don't know why it's draining the battery. But with it unhooked, there is NO draw in the battery. It's going to stay unhooked.

Sounds like the same unit. I've seen several with different names and colors, which are identical otherwise. I just got home from finding fuses. 250 milliamp was the closest I could find.

Bob.......NO problem with using 250ma fuze 'stedda 200ma. Remember, unlike voltmeters, ammeters are series (inline) installed. Everything IN thru one ammeter wire and everything OUT the other wire. And ammeters are POLARITY (+) sensitive. Unlike yer N-Tractor ammeter which is ZERO centered so it is semi-polarity sensitive. ...ie... (+) is considered charge and (-) is considered discharge. Now days, yer BelchFire-V8 uses IDIOT lites fer DISCHARGE only. Meters confuze drivers. .......electrical Dell

Another thing about battery drain I learned just a few years ago. A IH 1586 always came up with dead batteries when left unused for a couple of months. A check on battery drain showed the normal drain of a few milli amps but I just happened to leave my meter hooked up for a couple minutes and bingo. The meter took a jump to several milli amps(don't remember the number, like 70 or 80 maybe). Unhooking the meter and rehooking it did same thing. I traced it down to the data center. Unhooked data center and drain was normal few milli amps. I sent the data center into be tested. They called me and I explained the problem. Had given them a written note with unit. They said they had been running it for like 48 hours and saw no problem. I said, the problem is when it is when tractor is not being run. They sent it back, did the same thing, no explanation just that it was fine. We all know that it is normal for a lot of vehicles with computers to show a considerable drain when first hooking up and then it drops off but this one works just the opposite.

Does the tractor sit outside? It might have the same safety module as the smaller tractors and those things are problematic. Not sure why you would be using the dc tap when all you need to do is check continuity to see if the seat switch is stuck open, or if it is another safety switch.

My bet would be on the seat switch stuck open, or the safety module. Been there, done those.
