I lost my overdrive on my 57 six cly. It was blowing fuses, Have replaced the solenoid with a new on from SI. Still no overdrive, do you think it would be the governor? Waiting on SI to let me know if they have any.

The governor can keep the overdrive from engaging, but will not blow fuses.
Time to get the shop manual and follow the troubleshooting procedures, rather than shooting from the hip. Lots of folks can give lots of advice, but nothing will replace hands on testing and knowledge of how the system works.RadioRoy, specializing in AM/FM conversions with auxiliary inputs for iPod/satellite/CD player.

As Roy said a Trouble shooting session is need to find the fault, otherwise we are merely GUESSING.
However with a "short" blowing a Fuse, the first thing I would look at would be the Kickdown Switch and it's wiring, ALL of the O.D. Wiring for frayed, bare and poorly connected wires.StudeRich

Correct diagnosis can save the cost of needless parts. Poor grounds, or in this case, unintended grounds are the cheapest fixes.Brad Johnson,

The governor initiates a ground. The Lock out switch is next up the circuit and is normally closed unless OD is manually locked out. Next up the line in the circuit is the kick-down switch that is also normally closed. None of these should alone should be capable of blowing a fuse. As you move to the relay positive current becomes part of the system and a short here or beyond could blow a fuse.
The first place I would start is to disconnect the wire at the relay that goes to the solenoid... no blown fuse and you've cleared the relay or wiring to the relay as the problem and isolated it to the solenoid or beyond.

You could also say WHEN the fuse blows - as soon as you turn on the key, or when the overdrive engages, or...?RadioRoy, specializing in AM/FM conversions with auxiliary inputs for iPod/satellite/CD player. In the old car radio business since 1985.

The fact that the OD engages properly and then disengages at 27 pretty well proves the governor is OK. As the governor releases it causes the relay to disengage which causes the solenoid to release. This is assuming you still have the original system. Later setups discontinued the use of the relay. Usually the fuse blows when the solenoid engages due to the current surge.
Make sure the kickdown switch operates freely. This is spring loaded and should move in and out freely. If it's hung up a little WD40 might free it up.
The owners manual calls for a 15 AGC fuse. I believe later systems used a 14 SFE (slow blow) fuse. You might try one of these. If all else fails try the shop manual trouble shooting procedure. It will guide you thru the steps necessary to test each component.American iron, real old school
With two tone paint, it sure is cool
Its got 8 cylinders and uses them all
With an overdrive that just won't stall
With a 4 barrel carb and dual exhausts
With 4.23 gears it can really get lost
Its got safety belts and I ain't scared
The brakes are good and the tires are fair.

Well we do seem to have the problem fixed, the new wiring went in , just in case, a new relay on the firewall, a new 15 amp fuse block new style, Then found out the BRAND NEW Solenoid was also defective, so I have it running with the old original back in and on the road test all worked well. Up, down, kick down, all as it should do. But I do want to have another Solenoid to have as a spare. Thanks for the comments and help, see you in Dover if all keeps working.Evan Severson
