looks good...best part is the VT plate
is that an e-type jag in the background?![]()
Thanks, & yup, not mine (thankfully) it is waiting for new rad hoses, total PITA.
Spent the afternoon getting to know the AC system. Finally have some definitive information.
The 60 series amp will not work without the coil signal. I did not verify if you could just put power to the black wire (I think that would actually work, but I will let someone else fry their amp).
I have the tach translator set to read too high, the amp has no problem reading the signal, since it operates off the same circuit as the tach, the tach reads too high, so the amp thinks there is plenty of rpms.
The 62 amp is a direct swap, unplug one, plug the other in. The 62 amp has an extra spade terminal on the side that has a line going to the starter magnetic switch circuit. This line cuts out all the functions of the amp when it gets power. That way when you turn the key to start, the amp shuts down and disengages the clutch. If you plugged the 62 amp into the 60 AC system it would be a good idea to always make sure the ac switch is off before trying to start the engine.
This sounds relatively simple as I write it down, but I spent the better part of the afternoon fiddling with the system because it would not work. It turns out that my pressure switch spontaneously decided to crap out, nothing to do with all the things I changed but crippling just the same.
I do not think I really want to vacuum out the system, pull the evaporator again and replace the pressure switch, I just unplugged the pressure switch, jumped the two terminals and the system runs continuously (when the ac switch is on). I guess I just need to turn it off every so often to simulate cycling the pump.
The simplest way to make the system work manually is to jump together the yellow wire and the black-white wire on the amp, this still allows the use of the AC button, but bypasses all the functions of the amp.
Since the Dakotadigital unit is going to need to stay, I mounted it and the glow plug relay inside a little tackle box and bolted it to the fender as well. I have an "inductive sensor" coming in on monday that I will put in the bellhousing (pulled the starter motor and measured where the flywheel teeth are) to run the translator and hopefully get the right signal.
