Alie&Jim's Carrilite Posted February 17, 2017 Report Share Posted February 17, 2017 We have a Generac GP5500 generator mounted on the back of the truck. How can I wire an LED light inside the truck that will tell me if the generator is running or not? It is a manual pull start so I do not have a 12v charge back to the battery to work from. There is an hour meter but it is 120v driven and I really don't want to have 120v running behind the truck dash. Any thoughts? The genset runs 6-8 hours at low throttle which is fine for most moving days. The issue is that there is a low oil shut down that gets tripped on really bad roads like portions of I-10. Bouncing or turns that slosh the oil in the crankcase trips the low oil shut down. On hot days I'll run an AC for the last 2-3 hours to help cool the interior, as well as keeping batteries charged for the inverter that runs a freezer and several other items. I can e-mail the genset electric diagram to whoever can help here.

jeffw Posted February 17, 2017 Report Share Posted February 17, 2017 You could use a 120V relay to switch the ground on a 12V light on your dash.

Star Dreamer Posted February 17, 2017 Report Share Posted February 17, 2017 Usually they have a low oil light that comes on, can you piggy back off of that? It don't tell you if it shut down for other reasons though.

Jack Mayer Posted February 17, 2017 Report Share Posted February 17, 2017 Jeff's relay idea is the way I'd do it. Simply monitor the 120 volt output. If it goes off, the relay will trip a 12 volt dash indicator. Simple and effective. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

That's how they do it on reefers.... 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted February 17, 2017 Author Report Share Posted February 17, 2017 I like the idea of the relay, hadn't thought about that. There isn't anywhere on the bed that I can mount a light that would be easy to see in the daylight. Had thought about that though, couple of christmas tree lights mounted where the hitch camera would keep an eye on them. But the idea of a simple red or green LED light on the dash is what I like best. No low oil indicator light. It either runs or it doesn't!
