Ok, in addition to no water in the bubbler, there is no water in the generator anymore...
Upon inspection, there is a crack in the bottom of the box. (I'm using one of those 6 x 6 x 4 inch pvc boxes.) I guess the water froze and cracked the box. I don't guess the too much vacuum did this? I wouldn't think so.
Anyway, how should I keep the water from freezing next time?
And, I checked voltage going in the map enhancer and at idle it was about 1.5V. I flipped the switch over to enhanced and cranked the knob all the way lean and it dropped the voltage down to .5V but car doesn't respond.
While I had the voltage meter hooked up, I was seeing what increasing the rpm did to the voltage and when I stepped on the gas (as engine loses vacuum) the voltage jump up somewhat. Once the engine built up vacuum again at that increase rpm (which should be a greater vacuum than at idle), the voltage going into the enhancer was slightly
lower.
So, since a higher rpm takes more gas and that higher rpm has
less voltage than a lower rpm, wouldn't cutting the voltage with this enhancer actually give the engine
more gas?
Let me know if all this makes sense to you...
