I have a Bosh MJB mag for my L and it has no spark. The points look good though they did have some white powdery corosion around them but were not burnt.Is there a way to check the condencer and the coil out or is it a thing where you replace parts until it works?
 
Clean the points as Hoss suggested. If you still
have no fire check the mag's magnets for magetism using a flatblade screwdriver. Hal
PS; It could be a weak coil too.
 
Most Mag problems that I run across here are the result of corrosion. Take it apart & clean every connection, including the points. Set the points close, about .012. Setting the points close keeps the points closed longer, allowing the mag to build up a bigger charge before firing. Good luck.
 
thanks for the advice, I"ll check it out and get back to what I found. I do have a Case mag that will kill you with the spark but I"d rather put on the Bosch.
 
Must be catching my Bosh on my LA when south and there is no spark took it off its in my shop waiting for me to stop playing with trains and go though it again.
