avant Posted August 30, 2015 Share Posted August 30, 2015 Hi Everybody! First post to the forum, and I have been reading/visiting sites generally sopping up info like a dry sponge. I am just getting into g scale, have a test track set up, decided on battery powered running gear, have gotten a collection of engines and started some projects. I got a few engines, new and used, put together by my suppliers ( rld ) and have upgraded a couple Aristo dash-9 and usat sd40 to airwire. Living in Reno has gotten me down to the Sparks yards to trainspot a couple of times and I'm just absorbed... My question is about my upgrade of a USAT sd40 with a drop-in Airwire board. When I flip the motor switch I am getting a high frequency beep off the airwire speaker. I've read that this indicates the voltage controllers are over loading. IF I start running the engine the beep usually goes away. I am looking for someone who has run into this before or has confirmed what the issue is with CVP. I have tried unplugging either drive unit in turn to see if either one had a short, no difference. Also, the interior and cab top strobe are extremely dim, almost non-lit. I am looking for info as to what this might be related to and any fixes? Could this be related to the beep? I am using an 18.5V li-ion 9ah battery. I wanted to ask here before going to CVP, as, from what I have seen, their answer is always, send the board in for testing... Thanks for any help Robert Quote Link to comment Share on other sites More sharing options...
enginear joe Posted August 31, 2015 Share Posted August 31, 2015 There are guys here who can help. I believe that Dennis Sirrine is heavy into Airwire now, and also could help you. I only know to get him, by posting replies on his Utube videos! Probably not the best idea? If I started right now, I would have gone with battery. When I started, the life of the battery and their price and weight, just made it un-attractive for how many diesels I want to run at once. Add to that the price of control and separate sound cards, Shew!!! Stainless used to be fairly cheap back then. I just didn't realize how cheap. At least now Lithum-Ion batteries, and cheaper track used, makes it really attractive choice to go with battery. I know nothing about Airwire, sorry. I bet Ray does.

So far I love batteries, EXCEPT, batteries don't give your accessorized cars power, and running power to the switches and stuff will reduce the benefits of the batteries a fair bit... track is actually a fairly decent way to distribute power, so I still might power the track!
