Fuel gauge stopped working, reads all the way to the right (points straight to the passenger side). So, something (ground or sender, or possibly wiring) has gone bad. I don't want to drop the tank, may have to find the wire on it's way there and interrupt it instead (don't want to mess with the firewall connector if I don't have to.)
Put the dash back together after removing the PRND21 indicator, sanding off the rust (where the indicator wore off the paint) and lubricating it with grease. I now know what gear I'm in!
Read the operators manual, and found all four of the spot floods in the back work.
Something else I won't have to replace. I also now know that the GEN1 and GEN2 lights don't exist on the M1010, and the idiot light next to the voltmeter is a "door ajar" light for the rear doors... though the bulb is burned out / socket melted, so I suspect it wasn't working right anyway. I'll probably mount a 12V voltmeter next to the 24V, and put a momentary SPDT there, so I can momentarily check the RV batteries, or it'll normally read the 12V value with the ignition on.
Looks like there's enough space in the battery tray to hold both Group 34 Optimas, so I may modify the tray to put them both in the rear tray, and mount the RV battery in the front tray. It would make charging wiring much easier, and save space in the back.
Looked at the "broken" right front shock, the upper mount is not broken, the bushing is missing! Shocks look like they may be original, so I'm thinking I'll take it in for new shocks and maybe an alignment / steering diagnosis, because the wheel isn't quite straight. Rear shocks are yellow Monroes, so they look OK for now.
I was going to mount a DIN sized radio in the front, but the stock radio is a shaft type. I ordered a Pyle shaft type AM/FM/SD-Card MP3 player instead, and I'll use the DIN radio (with enclosure) in the back for a radio in the rear. It was only $25 for the Pyle shaft-type radio, hopefully it fits. Since the side flood lights are missing, putting the radio in the stock location seems to be a good solution. Shaft type radios are getting harder to find, though....
Other than the fuel gauge issue, the old beast started up easy as ever, and took it for a 10 mile drive (and a burger in the drive through.) As much as I'd like to justify repowering it, the 6.2 runs too good at the moment... maybe I should put a 700r4 in it instead....
Building this into an RV that will fit into a regular parking spot, yet is off-road capable... it's a lot of fun.
