Snap-On MT-335 Coil Tester...question I inherited a Snap-On coil tester, # MT-335. The 2 secondary studs at
the top on the box(for coil output), have a spring on each of them. Something fits between them....but I don't have a clue. Anybody out there have one of these tools or knows what goes there? Thanks, Dudley |
Re: Snap-On MT-335 Coil Tester...question There should be a glass tube between the springs.
I live in Clovis call 291-0320 if you need any more information. George Day |

Like George said there should be a glass neon tube in there. Mine broke and I don't
know were to find another one. Bob |
Re: Snap-On MT-335 Coil Tester...question Thank you George...good talk!
Bob, is there anything written on it...any part numbers? Thanks |
Re: Snap-On MT-335 Coil Tester...question I don't see any markings on it.

Re: Snap-On MT-335 Coil Tester...question Dudley,
Maybe these guys will know where to get parts: http://www.vintagesnapon.com/forum/index.php:) |
Re: Snap-On MT-335 Coil Tester...question I have one of those testers as well as others like it.
I would not worry about the tube. It appears to be a sealed glass tube with who know what in between. The ends are coated with some kind of metal. I am wondering if it is just a way to indicate there is high voltage when you have the gap too far apart to have an arc. These are really pretty simple and effective testers. You just see how far an arc you can sustain when coil is cold and then heat it up and see if the arc severely reduces in length. |
Re: Snap-On MT-335 Coil Tester...question A FB member named (I think) 500KR collects owners manuals for all kinds of tools and such. He might be able to help you with the Instructions.

Thank you for the help! George Day, #2 post, said his tube "glows", so I'm thinking that it's a neon tube of sorts. I have no idea what it does( filter or load?) for the secondary,...I really don't do electricity. I will try the Snap-On sight ............. http://www.vintagesnapon.com/forum/index.php:)................ when I / if figure it out, I will post the find. |
Re: Snap-On MT-335 Coil Tester...question Be CAREFUL, dj,:eek:
That dude'll CURL YOUR HAIR!!:D:D:D Buster T.:cool: |
Re: Snap-On MT-335 Coil Tester...question Yep....a cheap wave

Re: Snap-On MT-335 Coil Tester...question 1. I called Snap-On,....no help.
2. I haven't used the web sight,..but I did look..I didn't find it easy too navigate, maybe you have too join. 3. But I did get this far, it is a " neon pilot light ", when it gets warm/hot. I would think the voltage would have too be very high, say maybe 25,000 volts? I like tools that are complete, I'm sure they put that there for a reason, right? |
Re: Snap-On MT-335 Coil Tester...question For your Snap-On tester I can email you a copy of the instructions. The tubes are called Geisler tubes and seemed to be used in all the old distributor testers such as Sun(now Snap-On owned) Allen, Weidenhoff and others. Snap-On used to sell a small ball point pen styled tester to check spark at plugs. It also used a Geisler tube. My email is sponge19501924@yahoo. Of course no charge for info.

Thank you for the information! For some reason, your email is not working when I tried running it. If you click on my name, you can send me an email of the instructions. Thanks again. |

Re: Snap-On MT-335 Coil Tester...question Dudley,
Maybe the neon bulb is used to determine the polarity of the spark from the coil during testing. See this video on U Tube: https://www.youtube.com/watch?v=OKPPbLXNOt0 The neon glows around the left "pin" of the bulb with a negative voltage applied and the other "pin" if a positive voltage is applied. I remember seeing neon bulbs hooked to AC in old radios with vacumn tubes that glowed around both "pins" as AC current changes polarity 60 times a second so it appears that both "pins" are lit at the same time ... Most pilot neon lights on radios ran on about 100 volts. Notice that the fellow in video used eight 9 volt batteries or about 72 volts for his experiments. |
Re: Snap-On MT-335 Coil Tester...question dj I will send the info. Dan
