K-dot-B Posted May 27, 2024 Posted May 27, 2024 (edited) Setting the DC voltmeter to Rectifier Bus 1 (шины ву I) shows voltage even if that bus is without power, as demonstrated in my track. I did some testing and it seems that the DC voltmeter selector is simply "wired" incorrectly, and it is probably showing the battery voltage. The actual simulation of the electrical system is correct, Rectifier Bus 1 only works if the rectifiers are turned on, or the batteries are coupled to the rectifier buses.

Apparently rectifier connects to battery bus when battery is low, but can’t find anything out beyond that. Probably have an electronic schematic around somewhere… Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com

Probably have an electronic schematic around somewhere… I noticed this issue because while the voltmeter shows voltage on r.bus1, none of the consumers that are fed by it turn on. I tested this in a cold helicopter, only using the batteries as a power source. I used the list of systems powered by r.bus1 given in the CWAM manual (section 2-73.2) and turned them on one by one, first with just the batteries enabled, then with the batteries tied to the rectifier bus with the guarded switch. With just the batteries enabled, only the No.1 fuel pump and the formation lights turn on, however those are stated to be powered straight from the batteries in a different section. If the reading on the voltmeter for r.bus1 was correct, then things like the pilot and CPG fans and the CPG windshield wiper should be functional, but they are not. They only work if the interconnect switch is enabled and the rectifier buses are properly powered (the ARK-U2, Greben and SPUU require AC power as well.) If we assume that the developers implemented the electrical system correctly (which they appear to have), then the most likely explanation is that simply the voltmeter reading is incorrect. I believe the rectifier and battery buses are connected automatically only if the rectifiers are running and are able to supply power. It makes little sense to have a bus with big, nonessential consumers tied permanently to the batteries, especially if there is a manual switch that does exactly that. The electrical system is really fascinating with all its buses and interconnects, I'd love to see a schematic of it if you find one (and it's shareable ).
