If you choose to use an aftermarket Pressure Switch on your Electro Level
I system that has marginal current carrying capacity, why not rewire the
existing Relay as follows.
Have the Pressure Switch control the coil of the OEM Relay & the let the
Relay Contacts do the high current switching (it is rated at about 30
amps & already switches the current thru the Pressure switch to the
compressor motor at startup). The OEM relay is low cost item & easy to
replace if ever needed to be replaced. Don't add another relay to the
circuit.....decreases reliability with less time between failures.
This wiring concept change is also good for the EL I OEM Pressure switch
& Power Relay. See page 13 of my "Air Suspension System Operation"
booklet (Gene & others can tell you where to find a copy if you don't
already have one).
