air bag compressors tripping breaker

[rickywideglide]

installed rear air bags in my 1964,dual compressor ,has 60 amp circuit breaker,with truck running breaker will flip before tank is full @ 90 psi,relays seem warm to touch,any ideas to resolve this?i believe the relays are 40 amp,this was a full air ride kit,but only did rear,

What size wiring? What length between breaker, power source, & compressor/s?

I followed schematic shown,6 ga wire is about 7 feet from breaker to relays . should I separate grounds for relays and compressors?

I'll look @ my schematic but I remember tying my grounds together for the comps & relays. I do however have 'over-kill' as far the remainder of my GROUND system:

Engine block to frame = Each side of motor has 4ga batt cable to the frame (L&R rails ground to block).
BATT @ PASS rail & cab (relocated battery).
Frame rails to core support = 4ga (again, both sides).
Cab to frame rails = 4ga (both sides).
Rear x-member welded to rails.

Run a dedicated round and see if that fixes it.

ending up changing 60 amp circuit breaker with a better brand,went to lower psi pressure switch,been working like it should,still gonna add better ground from batt. to frame
