Where?

Post #1, second drawing, you referenced INPB and Q5, which are on opposite sides of the schematic.

 

This should be all you need as I see it.

Doesn't work.
When hall is "on" (draining to ground) an led is lit,
Q3 gets hot, .20A at 6v, 2.3A at 11v. Q4 also gets warm.
but when the hall sensor is off, nothing.

 

Should work, are you sure its wired correctly?
Double check the pins on the FETs
With Hall low Q2 and Q3 should be the only two Transistors conducting.

 

Alright, I changed things up, and used crutchow's recommendations:



It works, switching back and forth appropriately, but the current consuption with indicator leds is .93A at 6volts.
(I have two led place where the motor should go, with opposed polarity and dropping resistors as indicators)
As before, Q1 & Q2 stay cold, and Q3 & Q4 get hot.

 

Alright, I changed things up, and used crutchow's recommendations:

My bad I left out the resistor on the base of Q6. Should be as below.
You show Hall connected to Q5. You shouldn't need Q5, if Hall is open collector.

Thank you for looking it over again. Yup, I ommitted Q5 and used the open collector of the Hall.

It's late, and I discovered a new bag of mosfet parts that were junk,
then another, then I ohm tested all my pads against ground looking for whiskers, trashed a few npn transistors...

But, it's working!

Time to order new parts.

 

For what's it worth the circuit I posted in #25 that was originally missing the resistor would have been correct had I not forgotten to change the transistor for Q6. Changed Q6 designation to Q5 and use FET.

So we delete the 100k, and change the 2.2k on Q2 back to a 10k, lose an NPN, and gain a N-Mosfet. Interesting.

 

I just discovered and new wrinkle in my desire for an SPDT made from bjt's, it's over at this thread:

No need to reply, just adding it for completeness and archive purposes if I every get back this way again,
or someone else finds this thread helpful.
