Is there a limit to the number of street lights (rated at 12V DC) that can be run on one 22 AWG main run ?

The main power supply I am using is of the variable type with a maximum output of 17.2 V DC, 19.2 VA.

Reason I am asking is that I had 13 lights connected and one of them had its 24 AWG feeder wires burn up.

Am I doing something wrong ?

Thanks in advance for any advice.

I have miniatronics rail yard spot lights whose instructions say to connect the cable with the diode to the positive connection of the DC output of a transformer .

The power source I am using is the MRC Railpower 1300 that has both DC and AC output terminals. But the DC are not marked positive or negative.

How would I know which is the positive terminal of the DC output on the MRC 1300 in order to follow the Spot light instructions?

what is the best quick drying and bonding glue to use to join plastic to wood ?

I have a Miniatronics Rail Yard Spot Light 72-118-01. It has a diode and a resistor.

Being new to this hobby, could someone please tell me how to distinguish between  the diode and the resistor on this Spot Light ? One is of a brown color, the other is bluish.

thanks,

I heard somewhere that it is OK to leave gaps between sections (HO Scale) to allow for potential expansion.

How much gap should there be for HO Scale track ? Maximum/Minimum ??

Any easy way to measure this ?

Thanks.

Can anyone advise how to make connections with the Acculites Vampire II ?

could someone educate me as to the difference between bachman's LT #4 turnout and its LT #4 DCC turnout ?
thanks.

All below related to DCC operations.
How do you get power for DCC operations to EZ track ?
How do you determine how much power you need to overcome voltage drop on EZ Track ?
If you need more power due to voltage drop, how do you provide it on EZ Track ?

I have some experience with HO EZ  Track, but no experience with Flextrack.
Does the flextrack come in different heights and if so which one would I use for HO and how would I adjust to match with the HO EZ Track ?
Any issues with heights of the two different  tracks ?
What are the connectors to use between sections of the flextrack and between the flextrack and the EZ Track ?
how do you connect Bachmann HO EZ Track to Bachmann Flextrack ?
How do you cut the Flextrack for different lengths ?
Anything else to be aware of ?

Thanks.

could you please advise as to the difference between these two types of EZ tracks. I have the "normal" ones. When would one type be used over the other ?
