I would like to know if it is recommended or not to use a common power supply for all modules and if Jim has automatic polarity reversal turned off? on the DR5033s as recommended. Of course there can be other reasons for short circuits and I am using 15v and not 18v power supplies.
For YaMoRC devices with HBridge it is not !! Every HBridge needs it's own double Isolated Switch-Mode powersupply. !!!??
Not complying leads to Common Ground wiring, which is NOT supported and might and will damage the equipment !!!
?Having a power supply drop from 18v to 8v at switch-on is alarming and does indicate a permanent low resistance somewhere.?
That very probably is because of the common powersupply.... but very, VERY alarming indeed !
