So been working on the rear air suspension of my Electro Level 1 system because i accidently dropped the right side (well i just tried the switch....it dumped the whole bag in a split second) and it wont refill.
I replaced the DANA compressor with a known good one because mine was weak along with a faulty check valve and pressure gauge. Got it all back together and still no lift....right side doesnt build pressure but the left side doesnt.
So i hit "travel mode" to see what would happen....i assumed the bags would balance left/right but nope....right side stayed the same and so did left with no visible pressure increase on gauge.
All solinoids have power and click.....right side raise solenoid (one with blue line) works and allows air when i blow in it....lower solenoid (middle of the three) allows air to flow when i blow in it....the last solinoid works(one with yellow line) but i cant verify air passage because i have remove a bunch of other stuff in the way.....
So heres my thought on this.....one would suspect the bag or line to the bag as having a leak because the gauge never builds pressure (right side or travel mode) but there is zero audible air leakage....which would leave me, you would think with a plugged solinoid but that would build pressure, which it doesnt.
The other question i have is how much air should be coming out of the system at the solinoids? I would think enough that if you plugged the hole with your thumb you'd feel it.....no?
