It's not the welding ability Tim, it's the stray current and what it can do to various electrical and electronic components.

I think this is what you meant?

Hi folks and sorry for the delay with the DMM tutorial, but I’m flat out.


I have just ordered a small number of the DMMs mentioned earlier in this thread. The retail price is $45 and I can supply anyone wanting one of these for $48, including postage to anywhere in Australia.


I will be using one of these as the training device.

I recently bought this one. Ok for the tutorial?

Hi Don, that DMM will be fine and any DMM can be used.


When I get the time to start the tutorial, if you are unsure about the setting being selected, you can post up a photo of your particular DMM and the settings for your device will be posted up.


Sorry for the delay but I am flat-out but as soon as I have the time, I will start posting up the basics of using DMM.

No hurry Tim, we appreciate your efforts

Hi Ranga, here is some basic info about different types of automotive relays.


This is info I already have available, but if there is more you would like to know about them, just ask.

Am I missing something? A horn connected using the first diagram would be annoying. Should terminal 85 be to battery positive via a switch?

Maybe the earth terminal (86) is being earthed by the horn button ?
