Thanks for the update, Curt. If by “next time”, you are planning to repeat the exercise in the near future, would you let us know how you get on? It’s just as helpful to know what doesn’t work as to know what does work. Here’s another thought: whilst looking for the cause of your noise, try holding,...

Hello Curt I was just browsing the forum; I don’t visit anyhing like as often as I should. Did you get anywhere with this? If not, a couple of thoughts: Your photos show cables resting all over on the engine. Ideally you need to get your cables routed as far as possible from the engine and especiall...

I wonder if anyone has used the PicoScope to look at the performance of a high-torque starter motor? The advertising hype states these starters use less current and put less strain on the battery as well as spinning the engine over faster. The first claim didn't make sense as the electrical power re...

Hi all, I'm new here and to scopes in general. I'm wondering if you work out the max speed for a given time. Example I would like to log for 4hrs using two of the four channels. A for voltage and B for current. Does the amount of channels of type of probe/clamp make a difference? Thanks in advance ...

I can't decidewhether to post here or in the diagnostics sub-section or even in the NVH section, but I want to invite comments and feedback on a test I played around with last summer. The test centres around using the 3-axis accelerometer (TA143) (and interface TA259) from the NVH kit to display the...

Hello David, Thanks for the email you sent with the .psdata file. In the email you helpfully mentioned that you were using a guided test. When I read that I had an idea what the problem would be: something we've all done before we learned our lesson - too small a timebase. Here's a screenshot of the...

Don't apologise, Dave: they won't take your 'scope away for posting here; I was just wanting to make sure I understood what you were doing, and, thinking you might have got more viewings in the other section. No matter at all. I've installed the 6.13.14 software - so thanks for the prod that there's...

Hello David You say: “..same result just a distorted pattern.”. Until I read that I was picturing a square wave on the display. Are you nor seeing a square wave? If you’re getting a distorted pattern, I can understand that it’d be difficult for the software to make sense of it to calculate duty cycl...

Many thanks.

When carrying out the Battery Test using a 4-channel 'scope, there's the option of using Ch C and D for an Extended Drop Test. The Guide says: " Channel C: Starter motor positive terminal Using a BNC to 4 mm lead, connect the red 4 mm plug to the positive terminal of the starter motor using the appr...
