I have tried searching but cannot find anything specific on how to wire ballast puppies up to the stock touch pad in my 03 SAN.
Does any one have some specifics on how to do this?

Just use the factory pump harness to trip relays as I did with mine:

This might help to. The wires marked PME are the wires coming from the relay box to the old arreator type pumps.Comment

Awesome. Thanks for the help guys!Comment

Random question as I am going to wire this up now. Are there differences in relay's I should be using? I am new to this, but feel comfortable wiring it up, just not sure on what to look for and dont want wally to help me at NAPA and steer me wrong.
Thanks!Comment

I set this all up this today and it didnt fire... I can hear each relay hitting/switching on both the fill and the drain relays, but the pump is not running. Pump works when put direct to the battery in both directions.
What else should I be checking and double checking?
Other question is that when I have this all wired up I hear one relay flip for each direction (one for fill and one for drain based on the key pad switch). That would only make the one lead (either black or orange) to the jabsco pump hot. Right? Don't these pumps need the ground to be active as well? Or do the relays act like the ground when not triggered by the switch? Or am I missing something fundamentally?
Thanks for the help.Comment

If you wired it like the diagram above it will not work. It shows the "common" side of then relay going to the pump, but the NO and NC contacts wire to 12V+ and 12V-. 12V never completes a circuit.
To make his simple to understand just think about one relay right now. Wire terminal 30 to one side of the pump then terminal 87 will go to the other side. This completes the circuit. Now when the switch is turned on the pump shall run one way. Wire the other relay in just the same. When it is turned on the pump shall run the other direction. Both relays will be paralleled to the pump.Jason

So do I have a ground connected to both leads as well as a power source? This way either relay, when activated, will be the only complete circuit.
I am not an electrical guru, so please excuse the stupid question but, is it bad if there is a + and two - sources are on it?
Thanks again for the help. Its starting to make sense.Comment

mnwakerider: let us know how it turns out, I'm hoping to do this to my 03 in about a month. Did you enlarge the intake openings? Where did you end up mounting your pumps? Good thread, I'm tuning in...
Thanks.Comment

Will do. I will start to take some pics of the process and such as well.
I added a third inlet with two 1" openings and will be using those and only one of the existing 3/4''s. I wanted to see how much a difference it really makes. More to follow!Comment

mnwakerider, my earlier observation was wrong. It should work correctly exactly as wired in the above diagram. Disregard what I said previously. I didn't think about the pump motor being reversible by swapping polarity. The way the diagram shows the relays wiring in should work. You might want to recheck your wiring to make sure it is correct.Jason

Core - Thanks for the help on this. The boat is at storage so I cant just run and check.
One question is where does the ground come from? As I understand it the relay will connect the + power when the switch from the key pad triggers the relay (which I can hear switch). But the other relay is not triggered so no current flowing to or from that relay. Right? I am trying to understand, but it seems to me that the other half of the loop is not connected to anything (+/-).
What am I missing?Comment

Looking at the terminals of the relay on the left, 30 is the "common" side of the relay going to the pump + lead. 87 is the "normally open" side going to +12VDC. 87A is the "normally closed" side going to -12VDC.Originally posted by mnwakerider View Post

When the relay on the left relay is activated, 87 closes to 30 putting +12VDC to the left side of the pump. Since the right relay is not activated, that is carried through the motor and through the "normally closed" 30 & 87A terminals of the right relay giving you the ground... Circuit complete, fill tanks!
The reverse happens when the right relay is activated. When the relay on the right relay is activated, 87 closes to 30 putting +12VDC to the right side of the pump. Since the left relay is not activated, that is carried through the motor and through the "normally closed" 30 & 87A terminals of the left relay giving you the ground... Circuit complete, empty tanks!
Whoever originaly created the wiring diagram was gifted with relay logic!Jason

That is a perfect explanation! This really helps, I did not understand that in an untriggered (or as you put it normal) setting the relay will act like a ground.
Now that I understand it will just have to go and look at it again. The multimeter will be with this time for sure...
Again, thanks for the help!Comment

MN, any updates on getting it to function properly? I'm in the early stages of the same build myself, just ripped out all of the old tanks and pumps this past weekend, going to start wiring soon. Where did you install your pumps? Did you add a 4th pump for a bow sac?
Thanks!Comment
