would this work with positive ground ?

Please explain question yea you have to have a positive and ground and then a tach signal. Are you using a reluctant wheel that grounds when a teeth passes or something?

Do you have a really old car that has positive ground?, that went away in the 50's for most manufacturers. I bet this won't work with positive ground though

can't say for sure. I installed mine on a 2000 full size Chevy conversion van with a 350 V8 and I'm very happy with it.

The only answer that I can think of is to ensure you have the ground on the correct side. If ground is opposite, the devise will not function properly.

I'm pretty sure that it would NOT... You should re'establish the original (or some) ground path FROM the device To the power source. Otherwise the device will remain ungrounded.

I would assume yes. It works perfectly in my above ground only the corners are a bit hard but that is due to the curve. An in-ground would be much easier! Enjoy!

There are many variations of this unit. To be sure I would call pertronix customer service. That's how I discovered I bought the wrong unit. I bought a positive ground unit when I should have bought a negative ground unit.

Normally you put the disconnect on the positive terminal in a negative ground vehicle. However, after checking throughly through the system on on of my vehicles I couldn't get it to work. So I put it on the negative post just making sure there no other connections. Use an ohm meter to tell you if it's OK.

Yes, this unit will only work when it's grounded. Always follow the manufactures instructions when wiring.

Yes, it has the ground plug acceptance if thats what you mean. You can google pictures of it for further confirmation.

To answer your question assuming the negative buss bar has screws you can use ring connectors to attach the ground to the buss bar. Make sure the buss bar has continuity between all the metal plates or it will not work.

As long as the heater plug is polarized (one wide prong, one narrow prong), there is no problem ... grounds are over-rated, not always needed. living in a "two-wire house with NO ground! yet still alive somehow ... retired electrician.

no it has a standard 2 prong 110v plug with no ground - you might be able to split the load from the power supply though,

Yes, I believe it would work because it has multiple settings for varying voltages. Please make sure the polarity (+-) is set properly before using it. Directions for how to set the polarity come with the adapter. If you don't pay attention, you may damage your unit.

With a standard 12v DC adapter. Look on the PCB and you will see a + and - sign indicating the polarity.

Okay, sorry. Amazon asked me to comment on this by saying "since you own this unit maybe you could answer the question" But evidently I don't own this unit, because the model I have has a ground post and 6 negative connections.. Sorry all.

There is a way to ground it, but you must do it through a separate amp. Hope this helps!

They have a common negative or ground. The positive side is switched through the regulator

yes, but you will have to run the ground to a good clean metal surface for it to work.
