Another bad thing about attaching the alternator output to the load side of the battery switch is fried electronics.

If the battery switch is opened when the motor is running bad things usually happen.
Without the battery to absorb the alternator output the regulator can't work fast enough to control the voltage and it gets spiky x1000.
That voltage wailing around rips through electronics like a buzzsaw, it's like hitting 12v devices with 220AC!


The correct way to connect the alternator output when using a battery cutout switch is to get the correct three terminal switch.
That switch will isolate the alternator output and properly remove battery power from all circuits in the car.

Had the battery tested and it was only doing 17CCA vs the rated 170CCA. Bought a new one and moved on
Hopefully I can take her out tomorrow again.

You can build the most awesome thing in the world but at some point, an 80yr old man in a crx is probably going kick your butt on the track... don't ask me how I know.

Not sure if you got the cooling issue fixed but I have a Derale fan and I love it, I would definitely recommend it. I think mine was about $100 for a 2 speed 12" puller. Right out of the box you can feel it is very well made. I was quite shocked at the amount of air it moves, one of the best value products on my car.

Here is a link to the one I bought https://www.amazon.com/gp/product/B004X ... UTF8&psc=1

I got to drive the car yesterday!!

I ended up putting the Spal puller fan on, changing the battery, installing a new ignition switch, and changing the tranny fluid to help with the shifting. She felt good.

As far as running warm, she pretty much stayed at 185°-190° (engine temp) on the highway but once I started up Lookout Mountain she started to climb a bit at the slow speeds (90° day). Engine temp was around 206-210° with the radiator temps around 220°. For perspective, Lookout is about 20min from my house. I parked her for a bit while I chatted with a guy who has an actual At-om and on the way home she never got back about 195°. I don't know if she would have kept climbing if i would have continued driving. This still might be an issue on the track. hummmmm....

But she started up every time with no issue. There are definitely some rattles that I need to address and the alignment is off again. More work but that's fine as long as I can drive her :D

Also with out the scoop, the air temp stayed around 122° so that's not too bad on a 90° day.

I also got one of these just in case

HAHA, that's the brand you linked, and I own. We won't go camping without it, the flashlight is handy, and emergency power back up is never bad.
