My first question was are your Rx 65/66 upgraded to 18 volts, as otherwise these are only recommended for 13 volts, and you could have fried both. Second what is the current draw including the 65001, which seems to be current heavyHello, everyone!
Thought I might give everyone an update as to my progress.
I finally decided to remove the LGB MTS card from my loco and the hardware required to transfer track power to the loco motor. Next I rewired the loco and tender for radio control (DelTang Tx22 transmitter with Rx65c or Rx66receivers) and battery power (4s Li ion battery from RLD Hobbies). I found that the pads A, B, and C of the receivers actually yield 3.3 v and the negative leads of the headlight LEDs should be soldered to them. The positive leads should be connected to either the L pad or the positive terminal of the high current Rx65 adaptor. All of the other pads P1 through P8 are wired with positive lead to the pad. I used a 47 or 75 ohm resistor in line with the LEDs to reduce the brightness to the desired level. The firebox is wired in with a full wave rectifier to the motor leads so polarity is always appropriate; the trigger lead for the firebox is wired to the negative lead so the LEDs will light when voltage is supplied to the motor). So far, so good. My big mistake was connecting the 65001 sound module to my "franken-loco." I thought that since the 65001 in analog mode was originally connected to track power I could simply connect the same leads to the motor leads from the Rx65 or the Rx66. Bad idea. Train ran for a few seconds, sound blaring. Then the sound stopped and then I stopped the train. I inspected the first the Rx65 which was extremely hot! I removed the 65001 and tried to move the train again. No luck. Nothing worked. I replaced the Rx65 with the Rx66. Really bad idea as I got the same result (extreme overheating and no LEDs on the receiver lighting up). Now the Rx65c has been replaced with an Rx65c adapted for higher current. It works fine without the 65001 (I'm afraid to try it with the sound module installed). Both of the dead Rx65 and Rx66 have been returned to my DelTang vendor for analysis. The original Rx65 is diagnosed "as dead as it can be;" I haven't heard about the Rx66 yet. This is getting expensive!
Does anyone know anything about the voltage requirements for the 65001 sound module?
Oh, for those of you who have made suggestions about the voltage required to run my Mogul - with all of the now obsolete MTS parts the Loco starts up at about 3 v and runs at nearly full speed around 10 volts. Seems much lower voltages are required if the MTS is removed. My 4s battery puts out about 16.5 volts when fully charged. I haven't operated the loco enough to run the battery down yet.
Thanks for all of your suggestions! My saga continues as I explore the world of sound modules.
