24 volt solid state turn signals

[Gunner]

Hi All:

My electrical knowledge being somewhat limited I am turning to this wonderful forum in hopes someone can help out.

The 24 volt solid state turn signal flasher unit (part #11613631) in my M38A1 Cdn3 is the same as in my M151A1. These are the 4 inch square boxy units with the cooling fins all over them.

Some small short somewhere in my turn signal system fried the M38A1 flasher.

Silly Mike; I found the short, but only after borrowing the flasher out of the M151A1 and connecting it up to the M38A1... you guessed it... two flashes and plllplpllhf! that one stopped working as well.

Three questions arise:

How can I protect the obviously sensitive flasher from such 'frying' in the future?

Are they repairable or is it plug and play?

Any one know of a source as I now need two!

Cheers! Mike
