edalweber Posted July 21, 2014 Report Posted July 21, 2014 I picked up on ebay a very interesting publication titled Autolite Electrical Equipment Service and Maintenance Manual, copywrite in the late 1940's. It has a lot of potentially valuable information and specifications on equipment used in cars of that period, which you won't find in shop manuals, particularily Plymouth manuals. For example, the Plymouth manual warns you not to touch the central nut on the horns which is directly over the thick aluminum disk(the armature). The Autolite manual gives you the gap specifications which can be determined with an ordinary feeler gauge. for the low note horn it is .052, for the high note .042, so that if it is necessary to unscrew this nut and the disk you can easily restore the proper gap. Seems to be a lot of other useful info, and would probably be worth buying for lanyone interested in doing his own electrical work on these cars. 1 Quote
