Dimming lights

when connected to shore power and using my Parallax power supply model 7300, my interior lights dim excessively when I turn on my 12vdc water pump. I have check my grounds and need some ideas.

Thanks

Check the battery condition, voltage and connections. You sttill need a good battery when hooked up to shore power.

What happens when you are not hooked up to shore power?

Not really, especially with a modern 120 to 12 V converter. I never use a battery when our TT is parked for an extended time (which, since the birth of my grand-daughter has been years ).

I would check to see if any connections to or on the water pump are corroded, or if the pump itself is defective.

It has a reasonably hefty draw, IIRC, so some dimming is to be expected...

that is correct. with this parralax unit, the manual says to disconnect the batteries from the circuit when using shore power. I will check my pump to see if it draws too many amps.

Now thats unusual...I've only heard of isolating the batt's during storage when NOT plugged into SP. Never heard of using the converter as a direct power supply, unless an emergency batt failure, or for short duration when the batt's are out during storage.

How do you charge 'em?

Lumatic is Correct...

... and so are you, zestojo.
If you have a failing battery in the circuit, it will cause the symptoms you describe.

If you have disconnected the battery, then it can only be blamed on the pump drawing too many amps (on top of everything else you have turned on, right at that moment).
You may have simply reached the "point of culmination."
How many amps is your Parallax?

I wouldn't purchase a converter with that caveat.
