Reversing Track Loop Problem!!!

If you have turned off power to the reversing loop, I'm at a loss how it turns back on by itself.  Also, the AIU is only good for 4 amps through the contacts, so I'd be careful about switching track segments with it.

Yea John, me too!!! I have a 4amp fuse for AIU. Haven't had a problem  in several years.

X2. How is the AIU circuit going on and off? How do you have it wired? A diagram to see? And how do you trigger it?

 Oh!! am I bad. Problem solved!! I did some revisions on the reversing loop last week. Forgot to isolate the loop at the switch so power the  was always on,duh!!! Wasn't paying enough attention. Will blame it on old age.

Lima, Use ACC(accessories) on remote & run thru acc terminals on AIU just like a switch. trigger it @ on/off on remote screen.

Think I will go to a toggle switch. John has me thinking on the amps even though it is fused. Tom

Mystery solved.   I couldn't imagine how it was doing it by itself.

 John, so embarrassed on this one. You got me thinking on how it was doing it, so: THANK YOU!!  

You never go wrong on this forum. Tom

Nice to know that I'm not the only one that has these lapses.

 Thank you, again John. Seems like the lapses get more frequent with age. See ya!! 

Cheer up Tom, it's not as bad as it will be next week.  Welcome to "middle age."

Tom;

No problem switching track power with an AIU, just get a decent Relay in between the AIU and the power. They are widely available and cheap.

Here's one from Digikey: RELAY

As I posted in another thread, Jameco has 16 amp relays on sale for 99 cents.  The 20 I ordered just came.
