I appreciate the advice.  My other locomotives worked alright with the CW80 so I sent it into Bachman to have it serviced.  They have received it fixed it the same day.  Had to replace the electronics.  Apparently as this was an older engine that had been in the dealer stock for a long time it was bad from the factory and the boards were shorting out.  They sure were efficient and called me when they received the engine and went over the problem and their recommended fix.  I have to give them an A+ for their service.

Thanks, I have an old Lionel KW that I need to check out.  Hasn't been used for years and it's 60 years old.  I'll test it.

I bought an NW-2 Switcher which was new in the box and when I tried to run it the CW-80 Lionel transformer shows a short after it has been on just a short time.  Can some one help me with troubleshooting and where I can take voltage readings to see what is wrong.  I've not worked on e-units before.  The bell will work intermittently but the horn won't sound.
