Can someone post what the control lever is supposed to feel like in the different directions?
On mine, I can feel the slight "clicks" in the up and down (accel/set and decel/set) directions, but in the front to back (resume? and off) directions it feels really squishy, and there's no definite click or anything to tell me that the function is being initiated. I've never tested it because I assumed it didn't work. Do you just push the lever up or down? I'll try it today...and if it doesn't work and the lever isn't messed up, I guess I'll pull the amp and see what it looks like on the inside. Can someone post a link to the tutorial mentioned earlier in this thread. Well, I can probably search and find it..I won't be a slacker thanks, -geoff

Careful. If you open it and decide you want it rebuilt, you might be out of luck. The main amp rebuilder wont work with one that's already been opened.

I swapped the cruise amp from the '77 300D into the Squash. Before the swap, nothing would happen via the cruise lever. After swapping, the cruise lever will accelerate the car, and it will hold speed below about 45mph, but only within about 5mph.
At freeway speed it doesn't really work. It looks like I need to tighten up the cable slack a little bit, which might help with consistency of speed. Also, maybe the extra slack might be keeping it from working at highway speed, as accelerator has linkage moved farther, and maybe too much cable slack to do anything????? I at least know that the original cruise amp is no good, so may open that one up to see what is going on in there. I also have an amp out there in Scar. May try that one too....

Can anyone help me out with the squishy feel in the control lever? Is that normal for the resume and off directions? Thanks, -Geoff

from what i have read, its just cold or weak solder points on the amp's pcb. its a pretty simple board, with about 30 or so resistors, a ic or two and a rectifier or two as well. just be careful with pull through when youre reheating the points and you should be fine. use a lower watt iron with a good tip. watch for bridging. wash the pcb with cleaner or alcohol and you should be ok. i say this from building circuits myself so....to me its second nature.
im thinking my only other problem now is something to do with the cable to the actuator or my speed sensor...when i set the cruise...it accelerates upt to 5 mph before setting. so if i want it at 65...i have to actually set it at 60.

I officially have cruise control in the Squash!! It only took 3 different cruise amps to find one that worked. And it was the one out of Scar!
So, the original didn't work at all, the second one only worked below about 45mph, and didn't hold speed very well, and the third works perfectly. I had no idea these old vacuum cruise controls would work very well, but my '79 Chevy PU has a vac unit, and it has worked perfectly for 28 years now..........

I haven't permanently mounted the working one yet, so I can swap them easily. I'm still just shocked at how well this old cruise system worked.

Geez Louise there is a lot of stuff in there!!
I couldn't see anything obvious inside of the one I opened up, which was the one that didn't work at all. When I opened up the can and pulled out the circuit board, it had that unmistakable smell you usually get when something fries, but all looked well. I guess I will try and re-melt all of the solder joints [of which there are plenty!] Ah, we'll see......... May attach pics later. This 65kb image restriction is just stupid! 100kb would be a much better limit, but I digress......
