Sierra Fuses
So on my last dive on the Sierra my scooter died. At the time I thought I may have just used up the battery, but tonight found the fuse was blown. To be more specific the fuse assembly had melted.
What would cause this? After I removed the fuse from the old assembly I did a resistance check from load side to line side of the fuse holder, and found no short.
I replaced the fuse assembly (let's just say I'm not an electrician), and it does work now. But I would like to find the cause rather than just treating the symptom.

Re: Sierra Fuses
Maybe corrosion in the holder increased resistance across it-creating heat. What was the fuse rated at?
If this is Chad's old scooter, that is probably a fuse holder I installed years ago. Soldered and shrink wrapped in place?

it is your old scooter, and it is the fuse holder you installed, your craftsmanship is better than mine. It was a 30 amp fuse.dsteding wrote:Maybe corrosion in the holder increased resistance across it-creating heat. What was the fuse rated at?

On the corrosion front I would suggest filling the new fuse holder terminals with silicone grease to exclude water and prevent a new corrosion/resistance/heat cycle.

Re: Sierra Fuses
Man, sorry to hear that. I have had any issues with the fuse holder that was installed when I bought it other than the cap popping off from time to time... but thats just the cap.
As you know, the wires running to the motor are long so you can get the tail off and disconnect the battery. Long enough that is you are not careful, they could very easily get pinched where the o ring seats when you are putting it together. I would check the wires real good to make sure that has not happened... although if it did, you would think the bad seal resulting would have allowed flooding.
Not that it should matter, but which battery were you using? Did the fuse blow at the beginning of the dive or the end?

Re: Sierra Fuses
It is close to five years old then. All things considered, I'd expect it to be the holder.kitsapdiver wrote:it is your old scooter, and it is the fuse holder you installed, your craftsmanship is better than mine.

If it is still with the scooter, I had a Watt's Up meter wired so you could have it in the scooter. It should measure peak current, so if the motor was shorting and pulling too much current or something, you may see it using that meter.
That scooter was good to me for a long time, I traded it for a couple kiddos, I guess. Enjoy it.

Re: Sierra Fuses
Yeah at this point I think it was the fuse holder. I got the scooter out for a dive today, and was on the trigger for 35-40 minutes of it probably, and it didn't seem to give me any problems, although it's still doing a freshwater soak, so in a few here I'll have to open it up and check the fuse holder.dsteding wrote:It is close to five years old then.

If it was a short in the motor I would suspect the fuse would have blown today. My dive buddy today did say he was in second gear to match me, but I had a stage bottle and deco bottle to just his deco bottle. And he's on a Cuda so it's hard to compare the two.
P.S. I'm not interested in making the trade for kiddo just yet. I'll have to stock up on Strawberry Condoms.

Re: Sierra Fuses
Strawberry condoms obviously don't work at all.
Fishing line or other junk around the prop (inside the hub) can lead to excess amps and blowing the fuse.

Replace the fuse holder & fuse, slap a little lithium grease in there, and go diving.
I've found differences in fuse holders. You want one where it's a bitch to get the fuse in.
One of these days I'll post a burn test showing the difference between an old fuse holder and a new one. It's pretty interesting, in a scooter geek kinda way.

Re: Sierra Fuses
We had this problem once with Barb's scoot. Replaced the fuse and it hasn't happened again. At about the same time, Matt was going through fuses in his Seirra pretty frequently. I think it turned out to be a bad control module.
If you start running into the problem often, I'd call/email, or bring it up to Ray at Dive Xtras. He has been super helpful to me and many other local divers. They stand behind their products and are always willing to help out.
Good luck - Lauri

What Lauri said. In my case it began happening more and more frequently, and ended up requiring new electronics. Hope all it takes for you is a new fuse.

Re: Sierra Fuses
There have been a couple scooters lately that kept blowing fuses due to the failure of the electronics. That's pricier than a new fuse so hopefully it's not that.

It sounds like he was going thorugh fuses. I hope the fact that the fuse holder melted means that it was the corrosion in the fuse holder.ldevore wrote:We had this problem once with Barb's scoot.

As far as the fuse holder goes, mine was melted too. Probably due to the high draw from the defective electronics. My advice would be not to do any scooter dependent dives until you're sure you've resolved the issue. It would suck to be stuck out at alki reef with a dead scooter.

Brian's got a whole army of trained monkeys diving all over the Puget Sound. Kinda like the wicked witch of the west but underwater.

Re: Sierra Fuses
Well I had never had the problem before the bomber, and it crapped the bed in 20ffw. However as the scooter was building up to it's non-cermonious crapping of the bed it was traveling at half the speed of smell....BDub wrote:The was directed at Austin.
