I couldn’t get a good waveform no matter how I set my scales, any suggestions?

What paddle were you using?

You're on a Toyota COP, it appears, which are notoriously difficult to test with a secondary pickup. :( Strange as it sounds, but you may have better luck with just an alligator clip. Here's a couple threads worth reading:

I saw we’re you helped a guy on how to build a secondary paddle out of a old Honda distributor, I have a distributor off a 2000 crv 2.0 , would that work and if so could you link me to the instructions how, I would really appreciate that

I see no reason why that wouldn't work! :cheer: It will probably only have one or two pickups (VRS sensors) in it, as opposed to the three you'd get in an older distributor. But really, you only end up using two at a time anyway.

There's no instructions to link to. It comes down to fishing the pickups out of the distributor, then grinding enough plastic off the outside to remove the mounting bracket and magnet. You're left with the pickup coil itself and the wires connected to it. Connect one end to a scope channel, and the other to ground. I'll try to grab a picture of mine at work tomorrow.

I will say that the wires are quite thin, and in your case, 20 years old. :lol: They have a tendency to break if they're not braced/secured. A setup like Noah's will stop the wires from flexing too much.

Ok, I saw what you was talking about with the wires so small, I’m a New tech at Toyota, I just finished SD’s whole online class, I thoroughly went through the classes for the past year, I also bought a used verus and have been practicing with the scope, Toyota hired me and to my amazement no one uses a scope there, I got the chance the other day to break mine out , but you saw the horrible capture I got, I’m determined to be the first guy in the shop to know how to use a scope effectively,

Good to know Honda the exact same pickup for years and years. :silly:

The magnet is still in there, so start grinding on the end furthest from the wires. Eventually you'll uncover two Phillips screws that hold the magnet on. Spin them out and you're home free.

Here's the one I made if you're interested.

"Ground cannot be checked with a 10mm socket"

"Stackable banana plugs" should pull them up on amazon and ebay. It's either those or "safety banana sockets" you really need for something like that pick-up so you've got a female to plug your test leads into. If you use regular plugs then you'll also need couplers to connect them to your leads.

Pretty sure I got those from Digikey:

www.digikey.com/en/resources/connectors/...a-and-tip-connectors

Their site is horrible to navigate. :silly: But they have a huge selection of quality stuff to choose from. If you want to be specific, these are the ones I ordered:

www.digikey.com/product-detail/en/cal-te...KCT2631-2-ND/5765511

To be honest, I wouldn't get these again - they're excellent plugs, but the stacking feature isn't needed for the secondary probe.

Absolutely, as long as it's a two-wire coil. Three wire or more won't have a primary waveform that can be tested without tearing the coil apart. :silly:
