Is there anyone in the Philly area who has knowledge about the MEP-803a generators who could help me trouble shoot a no crank issue when using the main switch S1. Everything else appears to work. Just can not get it to start. PM if you are willing to help out someone who is not familiar with...

Can someone point where "T" connection in the below schematic is coming from. Based on the fact S10-1 Dead Crank works tell me the connection (wire 114C) from S10 to K2 (crank relay) is working, K2 is energizing and providing L4 (starter Solenoid) with power. I have not found the location of K2...

Looking at the schematic for S-1 it looks like all the positive terminal 2, 4, 6, & 8 should be tied together, is this done internal to the switch or does it require external jumpers. I started looking at the other TB to make sure their jumpers were in place, they all look to be correct.

Okay, put in a jumper, it did not fix crank issue, but fix one of panel lights which I thought was burned out, the jumper ties all lights grounds together.

Thank you guys. I just verified that all the wires were correct, and was not making sense to me. Just started tracing back from starter to see where the contraction was broken, I figuring it was one relays that was problem. I did not find that schematic, I hate the way they have the drawing...

I decided to open everything up to see if any wires were disconnected or broken since it was obvious the top lids were removed. Found mouse nest but all wires where they are supposed to be. Did figure out where contactor sounds was coming from, it was relay K18, pre-heater, the other relay with...

Here is both sides of the switched as wired.

The ones with the Diode, between 1 and 7 yes it is there, I do not see any other.

Hello everyone, First, I want to thank everyone here for this resource, I probably would not have bought this generator without having this knowledge base available. I never worked on a diesel motor so this part is new to me. I have a gas generator and work on gas engines all the time. Building...
