Thank's fellas,I'm having problems with my ballast pump the motors working and the lines are clear butit's not pumping water into the bladder.
Does anyone know how the actually pumps?as I would like to get it sorted out.

cheers,
glenn.

bryantomosivitch

double check if battery is charged, and were you in dirty water, if you were take a air hose and blow the lines out very carfurely.

glenladen

G'day Bryan,I had already pulled the pump out and tested it and the lines are clear of mud and other contaminates as it was the first thing that I thought of and the motor is working but is not pumping water in or out.

cheers,
Glenn.

take the pump apart and check everything inside, something could of loosened up (not motor). Also look at the directions it will show you how it works. It might need a new hose inside the pump. Im looking at directions it looks like there is a hose inside and three cyclinders rotate, and hose is raped around them. Im sorry im going off the directions. But take it apart thats your best bet.

glenladen

No worries,thanks for that I'll give it ago.

cheers,
Glenn.

Very unusual that this pump fails but I have installed a fuel filter in the intake line of the pump along time ago one of the first things i did to mine and have never had a problem with it,it self cleans is cheap insurce .Sound like the tube inside the pump might be kinked? Very simple pump and parts are  available sepretly.

bryantomosivitch

hey man how did you make out

glenladen

G'day Bryan,I'm working at the moment so I'll strip it down on daysoff and see what the problem is with it.
Aquasub,I was surprised that it wasn't pumping either as the motor was running fine and nothing seemed to be wrong with it.

AQUASUB

Are you sure its just pumpping dry ,be sure it is in water before stripdown.Do you have control of the pumps direction?Take the covers off and submerge see if bag fills or is pumpping out.

bryantomosivitch

i think the tube in the pump is kinked or ir clogged. like what aquasub said.

AQUASUB

Yes if so change it should work fine.

glenladen

G'day all,yesterday was the first time all week that I've had a chance at sorting the pump out,I had to replace the 3 pump cylinders wih new ones and the pump works fine I now has a suction issue going on that i will sort out today and test.At least today I'll be fully awake to focus on the model as opposed to finishing nightshift like yesterday morning.

cheers and thank's for your help.
Glenn.

AQUASUB

You know you can test the dive system on the bench and with the core out of the tube ,just connect a suitable tube and water container ,the pump will then pump the bag.

glenladen

G'day aquasub,I'll give that a go as it was pumping okay pumping from one container into the next and back again and then when connected to the bag,could be the lines are being pinched.

AQUASUB

Sounds good let us know how she goes.

Cymro

I just purchased the SB-1.  First trial dive and the ballast pump runs continuously, does not change with input from the transmitter, appears to be pumping out only.  So she will not dive.  Any ideas or suggestions would be greatly appreciated.  Thanks.

AQUASUB

Make sure with a voltmeter that the main battery is fuly charged and tx battery are as  well,if good then check cristals and connections.

glenladen

Hey cymro,mine's doing the same thing with the ballast pump,she's going down for a strip down to sort it out and dave I had to replace the pumps rollers and now she pumps like it's nobody's business.

If you cant find the cause of the pump malfunction i would recomend changing out the stock radio ,use a futaba type radio or jr it will work just fine with the stock main pcb board,all fail safes stay the same!

I used a 10ch jr and love it!

I gues this sub has a radio problem that Thunder Tiger needs to fix,but at least we can fix it as well.

b4256

i am having a problem with my sub blowing fuses. the standard 10 amp blew out while submerged and she sank like a rock.any suggestions? i am new to the hobby and purchased this neptune used. runs like a dream until it lost power.any suggestions you have would be greatly appreciated

glenladen

b4256 g'day and welcome check to see if you have any damage to your electrical components ie:electrical cables that may have been rubbing on some part of the model and baring the wire or binding of the motor,damage motor wires,poor connections between your speed controller,ballast pump,sensors and controll board.
Also did you find any moisture inside the model when you pulled it apart?,water or moisture could have caused the short if any had/was inside the model.
did you smell any electrical burnt smells comming from the model when you opened it up,have you had a look at the motor or is that running okay when you run it?.

cheers,
glenn.

AQUASUB

yes all the above ,especialy the lug screw connections on the pcb check corrotion and tightness same on all connections. dave

bryantomosivitch

hey guys its me again. I had the sub sit for 1 mouth. I think that batterys shot. She wont last longer then a few mins before the pump turns on. Can anyoby point me in the right direction interms of parts to . And what Amp is the fuse, i just want to make sure its a 10 amp fuse. Sub is reading 12.8 volts with no load. When i take it apart, a new radio system is going in.
