What was the founding of the first marine biological laboratory

I have a Scuba Pro X650a regulator. After having the unit serviced this winter I used it last month for the first time in St. Croix.

The first day of diving went fine. However, as the week progressed I noticed that when taking in a breath the regulator continued to trickle air at a very small rate. While not enough to be concerned about safety at this point it has become an annoyance both from the fact that bubbles continue to trickle past my ears and air usage has increased. This is an intermittent problem.

I had it looked at by 2 certified Scuba Pro Dive shops and they could not find anything wrong with it though one did lower the first stage pressure just to a bit to see if that would work. I also cycled the control lever position for “dive” and “surface” intervals to ensure that there were no sticking problems.

It does appear that the problem is intermittent and that it only occurs when the regulator is under water.

In addition is there a diagram in which I can use to troubleshoot this problem?

NOTE: this version of the X650 was not on the recall list of Scuba Pro.

Any help would be appreciated.

I have a scooter which has 2 batteries they sit side by side.i forgot how to connect them up.i know the RED lead goes to the +on the first battery .then there is a short RED lead in the middle of the two what post does it go on the first & second battery. + or –

I have purchased three 750-watt power inverters in the last three weeks. They have all failed to work on the second or third use. The first two were the same brand. I replaced an old one that ran for several years. I am using it to run a 4.7 amp 120-volt vacuum cleaner motor that pumps up my air dock. I have it connected directly with marine cable to one of the boat batteries. The battery outputs about 12.8 volts DC. The fuses don?t blow, just No Output. I am using a three-wire 120-volt extension cord and am, wired neutral, hot and ground to the AC motor vial an on/off switch. The motor works fine when I run house power with an extension cord from the dock next to me. Could I be, just unlucky with new inverters and need to buy a forth one?

I have the Intex Sand/Pump pool filter Model SF 20110. It’s been running real great for the last 4 months. However recently it has been tripping the internal overloads and I have found the pump motor to be very hot when I put my hand against it. I have tried several different solutions, such as a level ground platform that was clear of any obstructions, made sure that the motor vents under the motor was clear of anything that would prevent air flow. I used a non electrical type of lubricate on the impeller. When I would turn on the pump the rotor would not turn but only would hum very loudly and then slowly begin to turn. I also noticed that the motor’s rotor shaft would not turn to freely due the tightness around the rotor’s shaft. After using the lubricate the shaft would turn a little easier. I used an amp meter on the incoming voltage line and the motor would run at 4.5 amp. And yet it still overheated and tripped the motor overloads. I can only think that the motor is still not getting enough ventilation. I have check and cleared all the incoming lines and found nothing block the pumps input or output lines. Any suggestion?
