Quick Tip Sunday

AWESOME!!! Love it!!!

This is a great tech tip.

When I purchased my first 2 channel I made a call to the SO service center and bugged the heck out of them I'm sure. I asked them what was the most common repairs that they encountered with their units as I was self tought and was afraid of damaging my investment at first. 

They did mention this to be a critical fault. Stacking the grounds. 

That's a great tip Chris, in case someone wears out their original leads and replaces them with a non SnapOn set, AESwave sells a ground quadruple that works great also.

I found myself have issues running multiple amp clamps. David would that lead help?

What kind of issues have you run into? Does the signal get noisy? I can’t remember if I’ve run multiple amp clapms of my snapon. I’ve for sure run them on my pico without issue. 

The ground connectors.

Running both amp clamps on my 4 channel with my voltage leads, I have to get creative every time. The SO amp clamps dont have a piggy back and with the versus only having one ground terminal it can get frustrating. I need to check to see if aeswave has a a splitter.

I also run into it when I use my pulse sensor as it has a bnc to bannana pig tail and dosen't have a piggy back ground either.

I dont run into this with the pico. It's a problem only with my SO gear to include my vantage. 

My snap-on low amp clamp is a stackable lead. its one of those in the pics

one is the yellow lead, the other is the amp clamp

My bad. Now I feel like an idiot.

It's my transducer set up and my pulse sensor I have the issues with, not my amp clamps. I just looked to verify.

Sorry Chris and thank you for the correction.

Pulse sensor you say, that looks pretty cool. Would you mind a little show and tell?

Absolutely, I make my own custom pressure pulse sensors.

With the amount I have invested in equipment I often try to build my own gear when possible until the financial side catches up with my wish list. 

A few years back I had several classes and spoke with sevral technicians using pressure sensors in their diagnostics and I was hooked.

This was shortly after I invested in my 1st scope when I made my own PPS so my money was tied up pretty good on my start up. 

Anyhow I've decided to continue to use my own design because I know it well. Over time I've tweaked it here and there to have a cleaner signal and response. Plus since I use not just the versus and vantage ultra but a pico as well, so I make them all with a BNC connector and just use an adapter for the bannana leads depending on the scope in use.

This capture I'm sharing is a diagnostic that confirmed intake valve sealing issue I did last week. 

The blue trace is the PPS and the green is my relative compression cranking test off of battery positive. Red is ign event as the yellow is the in-cylinder pressure using a SO500 PT.

The sensors are used in the tailpipe and crankcase pressure plugged into the dipstick as well as vacuum fuel pressure regulators. It's a go to tool for many diagnostics.

That's awesome, I would love to see a write up on that case study. If I wanted you to make me one, how much would it be?

I'll be posting last weeks case study as soon as I get the chance.

I'm just curious if I should wait till it's a fix or update it as I go? 

As for selling I Haven't thought much on that. 

Chris look me up on FB. 

Either way is good.

Yes Mike it will help, I do it all the time. In fact that was my first thought when I saw that.

Sweat thank you David. That's awesome. 

That ground quadrupler works great for my pulse sensors also. 

Just awesome!
