1969 Power top. Electrical question


On the 69 Parisienne Convertible, the top motor switch is fed through a connector attached to the Bat aux connector on the fuse block. 20 amp. This push on pigtail connector also feeds the underdash courtesy lamps.

Question:

Why is the top motor not fed from the 30 amp firewall circuit breaker, like illustrated in the shop manual wiring diagram? Would it not make sense for the top to have it's own heavy circuit?

I'm probably going to go and feed it off this circuit breaker.

That does seem strange. I'm with you, I'd feed it off the breaker. I always thought the wire from the breaker went straight to the dash switch.

It should get power from the breaker on the firewall. I think it feeds a 'T', and the top wiring plugs into it.
It's all fairly large gauge wiring, something like 12 gauge as shown in the wiring diagram. I think orange with a black stripe.

The red plug certainly looks like a factory plug or adapter. In fact the feed to top switch red plug will only fit into the red adapter.

I changed the red feed to top switch plug body, to one that would fit into the firewall breaker (O/B) power feed. The top seems to have a little more go now.

 

It's like they made a running change to the harness in order to fuse the top motor to 20a.

The breaker is 30a

Please remind me to put the original power top switch in your next care package.

The contacts can be fixed.

Maybe, one of the other members with 69 convertibles could post a pic.

Way I found it, never questioned it wink

Are the courtesy lamps the footwell lights? I've got a number of their harnesses, they have a blue connector housing, it's keyed to only plug into battery socket you show.

To the best of my knowledge this is original hook up as found on my 69 Convertible. My Dad was the second owner and wouldnt have had the know how to make any changes to the fuse panel connections. My car is an early 69 model built in November 68

Yes, the courtesy are the footwell lamps.

 Hello Dave. Is that red connector not the top switch feed plug?

I see in your shot the red and green out from the switch to the purple and grey body harness to pump. And the heavy black wire that would be the feed to the top switch. Strange I see the red plug on its own.

Do you think that red plug should be connected to the blue male?

 it won't go into the blue connector as it's keyed differently.   There should be a larger gauge orange with black stripe wire hanging up there somewhere.

The red connector on your top switch should be keyed like this.  It has 2 tabs sticking out on the bottom right corner:

It will plug into the back end of this red connector that has 3 regular connectors on its T:

This red connector will then plug into the orange/black wire from the firewall breaker.   Notice it is keyed differently with only a single tab hanging down on the bottom right.

Here's the wiring for the footwell (courtesy) lights.  One is keyed to plug in to the fuse block, and then has a pigtail hanging for something else to plug into:

Or, for something slightly different.  I think this is from a 70 Parisienne convertible I parted out a few years ago.   Same concept, the red connector from the power top switch will plug into the back of the red connector seen here.
