Cummins intake heater not turning on

[NJMatt50]

I have no volts to one of my air intake heater. I only have 12v coming in from the power feed to the solenoids. Something is not triggering it to turn on. Any ideas where to look? Are there fuses? Thanks. Cummins 480ce

There is a 10 amp fuse in the air heater circuit harness. Assuming we are talking about a B/C series, look in the area behind the aftercooler on the fuel pump side of the engines.

if it’s your boat, maybe update your boat info.
Also some good reading on Seaboard site.
Good luck

Yeah I saw that post. I have 480ce motors but can’t find that fuse they are talking about.

I have the M-3’s. Can’t send you a picture because I ripped my air heater circuits out 7 years ago. Sorry.
