Has anyone got or ever had a way to measure the voltage on the spark plug wires ?
Looking to see what voltage is coming from the mags. to spark plugs.
Looking for a way to check spark other than the cheap spark tester to try and see a spark jump inside a glass tube in the sunshine, and look for a specific color.

The voltage is whatever the breakdown of the spark gap is. You don't want to ever drive a spark plug coil to open circuit voltage as I am sure you know you can quickly damage it.

Wider gap = higher voltage
Higher compression = higher voltage

I have found through experience that on gaseous engines, you can run the gap down to almost nothing whatsoever and it will still fire the cylinder just fine, and this is a useful trick for troubleshooting ignition problems. If you close the gap down and it makes it run better, you have a weak ignition part.

To answer your question more directly, I just use a known good spark plug in the open air grounded to some metal part. Even if it is sunny the shade from your hand should still let you see a good spark, and you can hear it too. If it sparks good then it is working

I have this on my wish list of things.

There's also cheaper tools, like

That one doesn't tell you a voltage tho.
I bet I could get the same result with my non contact voltage probe.

MEC, Thanks, thats just what I was looking for.
Need it for generator and Go-Kart racing 2-cycle engines.

MEC, this tester has been a time saver this week, and has helped me troubleshoot several generators that were a mystery to figure out what was wrong with them. Thanks for telling me about this !

MEC, Thanks for the tip on this tester, has paid for itself in 3 days of trouble shooting and help fixing generators, that were a mystery as to what was wrong with them.

No problem at all.
You never know with specialty tools like that. Some may get used once and sit on the shelf for awhile. This one should get used often.

Another item would be an inspection camera to help locate oil leaks. Anyone have a good one they can recommend?
Maybe one with a UV bulb.

I own and use a [URL="http://www.dewalt.com/tools/cordless-instruments-inspection-cameras-dct412s1.aspx"][COLOR=Blue][U]DeWalt DCT412S1[/U][/COLOR][/URL] inspection camera. It's a fantastic tool. It has a removable color display (removable so that you can watch it in one place while moving the camera around) and a tiny diameter camera that can fit into very small places. It's available at Amazon for less than $330.

MEC,

I visited our local Costco a couple of days ago and I saw they had one sale. I didn’t pay a lot of attention to it so I can’t give you any more information other than they have them in stock at the moment. Another possible issue is that sometimes one store will carry an item and others might not, but if you have a store near you, you might want to check it out. There was a large display of them at our local store and the products at Costco tend to be of relative high quality. I don't think this is an item that they normally keep in stock so they may not be around for long. Sorry I can’t give more detailed information. I'll try to take a closer look the next time I visit the store.

Regards,

Gene

Thank you.

I did quite a bit of searching and found this one.
Only one I've found with the camera and lights on the side of the head. Most are on the front so you need a mirror.

The DeWalt unit I linked you to has the lighting right in the 5.8mm diameter head (great size for small spaces). It is not a UV camera, but it does a great job of seeing things that are otherwise in the dark when you need it. It's one third the price of the one you linked to.

The head for the C2 Camera you linked to is 10mm diameter.

The C2 Camera has an 18" long cable for its camera while the DeWalt I linked to has a 3ft. cable.

Yes, thank you.
Lots of choices each with their pros and cons.
One I was looking at is pricey and could probably get by with one like the DeWalt (who Generac now owns!).

MEC,

I got a chance to stop by Costco today and I took a look at the inspection camera that they currently have on sale. I'm sure it's more a homeowners item rather than a professional tool. It may not be suitable for your needs, but some of our other members may find it useful. The camera has a 2.4" digital LCD display and a 40" flexible neck.

I looked it up on the internet and here's the link if you're interested.

Costco is selling it for $58.99 where I live in Northwest Indiana, so the price is right.

Regards,

Gene

Glad to oblige. I’m thinking of getting one myself but I’m just not sure that at this point in my life I’d get enough use out of it to justify the purchase.

One thing is certain though, if I don’t buy one and Costco sells out of them, I’ll need one the very next day.:D

Regards,

Gene

Gene, I've used my DeWalt inspection camera to retrieve items that have been dropped down the dashboard vents in our car. The tiny camera diameter made that possible as did the LED that's built into the tip of the camera lens tube.

One really neat thing about this inspection camera is that I can remove the display and put it somewhere that I can see it while moving the grip body all around.

I've used my inspection camera to find things as well as to inspect things that I couldn't normally see due to other things being in the way.

Thanks Skip. I guess I really should take another look at the camera.

When my wife and I moved from our previous home into our current one, I got rid of a small fortune in tools, (my grandfather was a blacksmith) some of which I wish I had kept. I gave a lot of them away rather than offer them up for sale and have someone insult me by offering me pennies on the dollar. (I guess it made me feel better to give things away to someone who needed it rather than to get insulted by someone's low-ball offer.)

I can definitely see the value in having a tool such as this. I've never owned this type of tool previously.

Thanks for your thoughts. I'll let you know which way I go with this. As I said, you sure can't beat the price.

Regards,

Gene

P.S.

I was just sitting here thinking about what I just posted above. Today (the 11th) is my 71st birthday. My wife already tried to talk me into buying it.
I think I'm going to go out tomorrow to buy myself a remote view camera. Thanks for the nudge.

5w-30 Mobil 1 Synthetic Oil

.

I was at Costco today and for anyone who may be interested, Costco has various weights of Mobil 1 synthetic oil on sale from now (10-12-2015) to October 25th. Their normal sell price is $36.99. The sale price is $26.99 with $10 taken off the price of the item at the register as you check out.

You need to be a member to shop at Costco. There is no coupon required to purchase the oil. This is a store wide sale and should be available at any Costco store. The price breaks down to about $4.50 a quart which is probably about as good a price as you're going to find anywhere. The sale applies to six packs only. Single quarts are not available for sale.

Regards,

Gene
