It's been awhile since I've been in the forum. If this is the wrong one tell me and I'll move. I'm try to rig two independent loops using 072 Gargrave switches which I've done before but I've lost the secret on power to the actual crossover. I've got power fine on A&B loops. Non derailing feature for both curve and straight is good. Just when my postwar 671 turbine tries to cross between the loops it dies. Something I'm not doing. I've had this set up before with an insulating pin between the loops and it worked fine but there must be something I'm forgetting. Any thoughts on this?
