Could someone please tell me where you put the circuit breaker and where the power is connected to pick up the 12 volts to the switch on a 67 vert. I am not sure where the circuit breaker goes in the wiring harness also, I assume it is between the 12v source and the switch. Also can I use any 30a breaker on this or is it a single use breaker only used for this. I am making my own harness for this so I don't have anything to go by and it was not with the car. Thanks EB
You may want to use a heavier gauge wire for this circuit. It pulls a lot of amps when running. Personally I ran a fused 10 gauge wire from the battery directly to the the power top motor and set up a relay system. 12 gauge likely would have been OK too but I had the red 10 ga. on hand. I am using the original 43 yr old wiring (will need to replace someday) and I found 8 volts at my freshly rebuilt power top motor when running. Lower than design voltage is hard on any elect. motor, so i set up the relay system. Now its a full 12V when running.
68ragtop455, Got the harness last week and works great. I still want to pay you for you postage. The package says $5.85 but I guess that is can. dollars. So you said it was about $8. Let me know.
Now about the power top. I have found a three position 30a switch and a 30a curcuit breaker so all I need it to wire it. My plan was to come off of the horn relay with 10 ga. like suggested earlier and then to the curcuit breaker then the switch. After that I would take two 10 ga. wires back to the motor positive-positive. My three way switch would send power to either funtion as the switch allows (up-down). I ground the motor at the rear by the motor. Does this sound right?
You said you ran your power straight back to the motor. I was not sure how that works.
Good to hear you got it already and installed too, boy you don't mess around!! It was 5.85 for the shipping and the little cardboard envelope was around 2.50 (I can't remember for sure). As I said earlier don't worry about it, but if you insist on paying the shipping $8 will cover it good enough. I'll PM ya. As for the power top motor, sounds like you got it cased. Likely could get away with 12 ga. but as I said before these things draw a lot of Amps and its cheap insurance. I did a relay set up right at the motor as I didn't want to rewire the whole thing. Thats why I ran the power to the back. For what you are doing it will work 100%. Also try to use a battery charger or run the engine when putting the top up & down to maximize voltage to the motor.
