Thank you all for the information posted on this forum, it saved me lots of cash on my recent repairs.

I had the proverbial fuse issue and another minor one.

Anyhow, I now have a tach issue, I think it is simply the lead from the alternator, but, don't know where the red wire connects on the alternator, any info?

I also am wondering if anyone know if our fuel caps are vented, I think the are. I had to replace mine and the new one doesn't seem to be vented; thus, I have ran into fuel issues.

The fuel cap must have a vent OR there has to be a vent on the tank itself. One or the other.

The tach lead should be a yellow wire and it connects to the alternator just below the battery charging cable on the alternator.

Your wire might not be yellow but that's the last color I remember the tach lead as.

I think mine is pink.

You're probably correct Jim. I'm not sure when the colors changed or if there were other colors used. It depends on the model changes and part # changes. :thumbsup:

Oh,I completely forgot about the fuel cap issue. If you got a replacement cap and got the "new" part #,I don't think it has a vent. The later production units had a vent hose added to the top of the tank,therefore the vented cap wasn't necessary.

Jody, I've sure learned that you can't compare old to new in many instances. I think the photo below is the right alternator. The connection marked "pink" is the one for the tachometer unless NH started using a completely different alternator.

Jim,thanks for the pic. Now you gotta remember it's been a while since I wrenched on one of these,my memory is starting to get a little fuzzy. :laughing: Maybe it's the class II that have the setup I was referring to. :confused2:

Thanks for all the help guys...I'm sorry I was a little slow in response, been a crazy year.

Any ideas how I can vent the old style tank, or get an old fuel cap? My original fuel cap fell victim to the Land Pride 2584 Finish Mower. :)

Best bet would be to have your dealer get the correct cap. Otherwise,you'd need to order the tank vent fitting and vent hose and cut/drill a hole for installation. I'm assuming the vent fitting is available as a service item.

This is the "correct" way,I'm sure you can probably find a "shadetree" method and save some $$$.
