Thunderbolt Variants and What They Mean.

[OwenLester]

This has been bugging me for quite a bit, and I'm posting this for behalf of my friend as well.

So, the basics. It's obvious that there's the 1000 single tone, the 1000T dual tone, and the 1003 three tone (and the 2000 and system 7000), but there's been tiny little variant differences I've noticed.

For example, the 1000A/1000B. I think that it stands for single/three phase models, but my knowledge ends there.

My friend is going to see a "1000ATSA2," which we both don't know what it stands for. I think A2 is related to the blower, but I have no clue what the "S" means. If anyone can list off the variants and what they mean, that would be great. Thanks!

The official service manual only lists 6 models: https://www.civildefensemuseum.com/sire ... bolt-2.pdf
Service manual for Series B Thunderbolt: https://www.civildefensemuseum.com/sire ... bolt-3.pdf
And it looks like the oldest Thunderbolts may only have had three phase models: https://www.civildefensemuseum.com/sire ... bolt-1.pdf

• 1000A

• 1000AT

• 1000B

• 1000BT

• 1003A

• 1003B

Suffix meanings:

• A = three phase

• B = single phase

As for the rest, I have not a single clue what they mean. I've seen a Thunderbolt labeled as "1000ASC" once. Couldn't tell you what the S and C mean.

Hmm, interesting. Thank you for the clarification!

This really helps such a ton, because this has been bugging me for AGES and AGES and to have finally have it decoded a little is awesome. I'm not the most knowledgeable about 'bolts and their blowers though, but to know what variants there are for them helps tremendously. It just puzzles me how some enthusiasts tell them apart.

It's almost like there isn't a wiki with this information already.

I know the Thunderbolt page is a bit of a mess, though. We're getting it sorted out.

The 4M blower is the quietest and smallest of the 3. The 5M I believe has 2 rims instead of 3 with no rim in the middle, and the 6M has the largest belt wheel (pully?) Of all of them.

Yeah, I’m aware haha. Thats where I got the “A/B series” stuff, my friend has a hard time understanding it though, haha.

Slightly off topic, but I appreciate the work everyone has done to make the wiki what it is!

Ohh, well, this bolt I had just seen, I actually got a picture of the blower box, but I didn't take too much of a look at the blower due it being freezing cold out...My friend said it may be a 5M, but I've had others say it's a 6M. If you're curious what exact bolt it is, I can link a video of it here.

Sorry if that's off topic, but I'm just unsure of telling blower models apart.

You don't have to if you don't want to.

And to answer some of the variant questions, the Thunderbolt you're friend is going to see is a Thunderbolt 1000T with either a 5M or 4M 3-phase blower. The "A" means it has a 3-phase motor (like said in posts above), and the "A2" is the later 5M and 4M blowers (A1 is a 6M blower), so you were right with it being for the blower! Still not so sure about the "S" though.

Ah I see! That makes even more sense. I'm not good with identifying blower models but that helps a ton...also, just to clarify, I'm the friend that's (hopefully) going to see this bolt again! I have pictures of it if you want to confirm if the model is correct. I also have a picture of the blower box. The model name just really puzzled me is all.

I'll place the images here

As for the video, here's the link to this specific Thunderbolt sounding. The video titles it as a 1000, but on the map it's titled as a 1000ATSA2
