Much like waterboarding, dashboarding can be very painful. I recently pulled the dash out of my Chevy G30 Hi-Cube Camper and out jumped a spiderweb of wires. Luckily most were connected to something, however, there were a handful of disconnects and “droopy wires”. Now, nobody likes a droopy wire so I ended up tracing back all the droopies I could muster to the two batteries.
First, let me say that the Haynes Diesel Engine Repair Manual came in handy with flow charts for diagnosis.
Here is a Before and After shot:
Before:
After:
There was a bit of work to do: Install new 4×6 front speakers, wire speakers, test/replace dash lights, install a 12V molex connector, and cut holes in the new dashboard: for the Oil Pressure Gauge (which is still not connected because of the rouge green and orange wires), Engine Temp and the right A/C vent. Oh and cut a hole for the stereo head until and cut A/C holes for the center dash.
After rerouting wires and A/C unit components I tested everything, starting the Camper to make sure I didn’t cut anything important. It started up and everything seemed to work. Then next day was spent screwing the thing back together and into the front of the camper.
The fun just didn’t stop there, today the camper refused to start. You’ll notice the dog house is off exposing the engine. I suspect a glow-plug problem. Maybe the glow-plug relay. I ordered a new one, we’ll see what happens now.
goodnite.
Ok, the glow-plug relay almost did the trick, now the light comes on and the glow plugs seem to be getting power, this does not mean they are glowing 
Since they still could light a test light and passing power even though they may be stalled. I will need an Ammeter to test each glow-plug. This will be a PIA.
Well I decided to replace the glow-plugs (GPs), some looked newer than others so this will be an upgrade and a sure start on cold days
The new AC-Delco GPs seem to have done the trick. Starts like a champ now.
Post Road Trip Note:
The GPs now take some time to trigger. This maybe an issue with the temperature sensor that triggers the GP relay. Now time to run some tests.
