Bobcat T770 2.2Hrs, No Power to Panel/Starter Switch, no idea where to look
So, to start off, this is basically a relatively brand-new M-series T770 loader (only has 2.2 hours, that's just from factory test + PDI). It sat in the lot since about February, I doubt anybody's started it. I've no idea what the lines or the fuel or anything else looks like; my biggest concern is that there's just straight up no lighting up or nothing. I checked the battery, it sits at a comfy 12.84V, tested it, it can crank the right amount of CCA, all the connections are good, no corrosion, so I'm golden there. It's a good battery.
But nothing lights up. The deluxe control panel doesn't flip on, the engine doesn't start priming, nothing, whenever I turn the starter switch. Safe to say it definitely doesn't crank either. I hooked up the service analyzer, and I get nothing. It detects the auxiliary when I put it on 'power', but it will not crank the engine and does not detect main at all.
So I take off the interior panels, pull out the deluxe control and the starter switch, unplug that all, and I start testing with my multimeter; I'm getting good voltage to the cab, but when I test for resistance, I'm pulling 108 Ohms at the control panel and starter switch when testing switched power and ground to frame wires, for both wire clusters.
So I check the fuse and relay boxes. All of the fuses are fine, none of them are drawing too much, none are broken, the relays have good continuity, no overdraw...
I'm at my wits end here, because I have no idea where to look. I'm pretty entry-level when it comes to electrical, honestly. This is basically a virgin machine, and I *really* do not want to start cutting into the wrapped up cables to start poking around for bad wiring unless it's necessary-- which, honestly, I don't even think that's where the problem is. To answer a question before it's asked, no, I don't need OEM specs or diagrams, I already have that as I work at a licensed Bobcat dealership. I just need advice on where I should be checking. If anyone has knowledge of M-Series bobcats or just electrical on off-highway equipment in general and can tell me what I should be looking for, I'd be greatly appreciative. I'm very new to diagnosing issues and I'm trying to get better at it. Thank you.
