I have one of the older black link ignitors and I'm trying to find out if it's a single, dual or triple channel?
There are no external markings apart from a part number on the socket
Are there any ways to identify one externally by the pins or any other means?  Do they all have 7 pins even though the wiring may differ? Is there actually any difference between them internally?
I pulled the guts out and see there's a part number on the circuit board which has a 3 in it so I'm assuming it's a triple? (sorry didn't write it down).
Also, if the link ignitor has more channels than required, Is it normal practice to just wire it using the pins for a 1 or 2 channel ignitor?
Much appreciated
