These 24 volt coils have been a problem for a few years now. At present, we know of no supplier or manufacturer that makes anything better to replace this one. One thing to be sure of is that you have your ventilation/fording system completely in tact because without the fresh air coming through the fording system the coil will overheat. We also have had customers who recommend adding a ceramic voltage reducer as was used on most of the 1960’s cars to help the coils last longer. Currently that’s the only thing we can offer to help.
