I haven't checked to see if there's still a blackened portion of the field where you barfed...
With the truck...Installed the pyro. Not the most elegant solution, but it's 3" gauge, so difficult to be elegant about it.
I suspect it isn't working correctly, either the gauge or the probe is pooched, which kinda sucks,(at least it was free...)but having just read an article on the subject sounds like it should be easy enough to test the thermocouple, the gauge less so, as I'll need a steady source of low voltage. I still have that auber (f.u.auber ins.) gauge in a drawer so I can hook it up temporary like, or swipe it's probe to see if things work.
(good read...)

It responds very slowly, and highest number I saw was 700F which can't be right. Locomotive breath was in full force on the test drive. (an occasional italian tuneup isn't a bad thing..

)
I'd just install the auber, despite the rage at the company the gauge inspires, but it's a 24v number.
Kinda sounds like a probe is a probe tho, so at least I can test that end.
Also hooked up the afterglow to a switch with a bright ass flashing led so it's obvious it's on. Timer would be better, but this works for now, and I advanced the timing a smidge. It's a ve pump, so it's a pain in the ass timing them properly (dial gauge and special adapter) so I went for the "crowbar to the left one metric C-hair" approach. Seems to have improved things. I'll see how it starts in the AM. May have to ad a couple more hairs...
