149 voltage regulators?

Ok, thank you for the correction.

The NAPA VR896 still has 4 posts, but the Gen post is located on the underside and angled at a 45* toward the Fld/Bat/L posts. A bit strange for mounting a wire. I'll have to plug the Gen post on before mounting the regulator to the tractor. Then attach the Field and Bat lines and leave "Load" empty. NAPA's online photo didn't show anything but the top view, so all you see are 3 posts.

Just an FYI for all.

Most after market regulators have gen post on the back.

I am debating on returning the VR896 and exchanging it for the VR898.

In looking at things, it would be rather difficult to test the v/r. I don't think one can get a test probe under the v/r to check voltage on the "gen" terminal when you consider how restricted the space is where the v/r mounts. I'm not sure about the earlier models, but on the 149 it is under the seat and right of the battery. There is only a couple of inches clearance in any direction.

The VR898 has the "gen" terminal sticking out from underneath and would be easier to test probe.

Just my opinion and FYI to all.

The 898 is not the correct replacement part. Not being able to get to the terminal on the back for testing is silly. If you ever have another issue with it, you can find a way to get a probe in there. Use a test wire if you have to. It's not that difficult.

J-Mech. It is not an issue of the "gen" terminal sticking out the back. It is an issue that the terminal does not stick out at all. It is turned 180 degrees and points UNDER the v/r. That is what is the issue. Most every v/r that I looked at has the "gen" terminal sticking straight out the backside including the one shown in the cub cadet parts look up. Also, almost every other after market v/r state that they replace both the original delco-remy v/r #s 1118981 as well as 1118988. The functionality is the same for either unit.

If Roland comes on and corrects my assumption, I can see no reason not to use the NAPA VR898 in lieu of the VR896. When it comes to electrical issues, I trust Roland's opinion over almost anyone else's.

When it comes to motors, I highly respect your knowledge and information.

I won't agree or disagree but here's what I will add.

The G or gen terminal of the V/R is essentially the A terminal of the s/g which is easy peezy to probe or clamp on.

It is my opinion, that when cross referencing a part from OEM to Aftermarket, get the part that matches (or closely matches) OEM specifications. The original Delco 1118981 crosses to the VR896, and that it the one I would use.

I don't see how it's an issue. I've mounted (and so have countless others) the VR896 with no issues at all, so I don't see why it is you don't think you can do it.

Both the 1118981 and the 1118988 cross over to a VR896 or a VR896SB. Neither cross over to a VR898. So, what is your point?

Well, I appreciate what you are saying.... but Roland isn't the only guy who knows how an electrical system works. A voltage regulator is, after all, something a mechanic would fix. Pretty sure I've worked on several. I'm not saying that an 898 won't work.... I'm saying that I can't find where it replaces the Delco Remy one originally installed. I also don't seem to have any of my Echlin part books anymore to see what the specs are. I'm trying to figure out how you came to the conclusion it will work, outside of it "looks" like the original. Not all regulators are created equally. That's why there are so many part numbers.



I too would stick to the VR896. I DO however want to know what the difference is between the VR896 and the VR896SB, as they both show as an acceptable interchange, and vary $20 in price. So, what is the difference between them?

The only problem is the VR898 does not cross to the original V/R number. Only the VR896 does. The 898 crosses to these numbers: 1119576, 1118999, 1118997,1118993, 1118779, 1118381, 105114A, & AT11855. The 896 crosses to these numbers: 1118988, 1118981 & 12336883.

So, you need to use the VR896 because it is the correct one.
The VR898 is correct for the Original, 70, and 100 models only. I believe it is because they have the push button start, so the 898 is different internally to handle that.
