DOA Neptune SB1 Tiger Thunder Seawolf - need some help

[Sinksalot]

No wonder since it seems you, Sir Sinksalot and Bob have cornered the market and bought all the boats left out there. :p

I had a few people ask for a Neptune, They didn't want to buy one off ebay as just about all sell there broken in some way, even know the sellers say they working. Also alot didnt come with radios. So they asked me to buy and fix them for them and buy 75mhz radios, as they all wanted to run them in a deep pools. Buying original Neptune electronics is all but impossible. But things can be made to work in a Neptune. to replace the broken parts

Never bought one, but I’ve gutted a few and fixed them. Mostly leaks from cracked pump tubing and over tight seals.

Finding any parts for this boat is almost impossible,

Yea even testing the Neptune dry, the pump would fill the yellow bag with air. If you hear the pump turn on and you tried both directions, then the pump rollers must had broken off from the pump shaft and is most likely broken. If you dont hear the pump turn on, try feeding power directly to the pump.

I hear the pump in both directions. So I guess time for a new pump.

Thanks guys for the comments. All duly noted.

I fear the bag is not working as I don't actually see inflate. I suppose I would see that with the naked eye if it would work.

Sorry was away for a bit. The electronics on the Neptune and the seawolf that fail alot are the ballast pump controller, pressure sensor and the ballast pump. I had to replace all those electronics on three Neptunes already. I am working on 3 more Neptunes This time one for myself. Oh also the yellow ballast bag, the outer nylon starts to tear after a few years of use. Make sure to use some O-Ring Lubricant on all the o-rings, as you don't want the hard to get o-rings to dry out.

At least you have a parts boat. Finding any parts for this boat is almost impossible, and when you do, the prices are outrageous. The pump on that boat is crap. I tore a few down and fixed leaks, but it’s been a while. Get with Bob as he’s done several with mods that worked well.

Update:
The 15A fuses did the trick, both boats are now showing signs of life. One of the benefits of having two boats is that you can cross compare stuff and try to eliminate faulty parts. As it turned out the RC transmitter from the first boat (which was just "sold as is") is toast. I had a bad feeling when I touched the sticks and they had some strange resistance. The transmitter from the "perfect" boat has normally operating sticks and can work for either boat after moving the quartz.

As for the boats themselves, turns out the "perfect" boat (tested before shipping, yeah sure, that's why there was no fuse in it) has at least one servo not working, no pump working and no bag inflation. Might be all related to the same controller, don't know yet. Whereas the "sold as is" boat has actually absolutely everything responding. Even the emergency mode works (transmitter off, pump comes on).

So the next test will be to put the running boat into the bathtub and see whether it has any leaks and whether it can static dive. Glad we have a long weekend coming.

Hey, at one point WE ALL were the new-guy dumb-ass and we progressed

Well, I got the first part of your line covered. Let's see whether there will be a second part. :)

15 amps if memory serves.

Thanks, I'll roll with that.

Good call, Casey!

You just beat me to it: Upon further inspection I discovered that fuse holder and started to go through the assembly instructions. Sure enough that's a fuse holder (but no fuse). Just ordered a kit of fuses. The manual doesn't mention what kind (Amps) it should be. Do you know?

Would have been nice if they had mentioned that somewhere. Oh well.

PS: I'm glad I posted this under the "Silly newbies questions". I'm sure there will be more as I try to revive these two boats.
PPS: Thanks for chiming in. Very glad to have some experienced folks on this thread. I know I'd be lost without you guys.

Hey, at one point WE ALL were the new-guy dumb-ass and we progressed because 'those who came before us' passed on what they learned. Welcome to the Tribe.

I’m sure this is a silly question, but have you checked the fuse?
