| Check your entire system visually for any loose connection, broken hoses or vacuum leaks. |
| |
| First start with the engine shut off and no electricity through the system. Perform a normal VISUAL CHECK: |
- Is the jar damaged?
- Is the lid tight?
- Any distorted or cracked hoses or wires?
- Anything else broken or looks suspicious?
- Visually, is any of the fittings and electrolyzer lid seem like it might have or develop possible leaks? (Loose or missing glue, gasket, etc.)
|
| Now, still with the engine off, go into a more rigorous mechanical inspection: |
- Verify that all passages and check valves are proper and allow free flow,
- Blow through ALL the hoses because they might be clogged with dirt or baking soda residues,
- On a multi-cell system, check each fitting on your collector/manifold,
- Blow through the check valves and verify that they are closed and open as needed AND IN THE CORRECT DIRECTION of flow.
|
| NOTE: the check valve on the lid of the jar should only allow for air to go OUT of the jar (this for safety purposes, to prevent pressure build-up) and air should never come into the jar via the valve. Unless it is broken (check it by blowing thru from the top - it should be shut off) the check valve will not create vacuum leaks. |
| |
| A major issue is vacuum leaks and the most common leak is from the jar lid not able to seal properly. At first you may be able to tighten it enough by hand, then you need more force, and after some heat and time, it warps just a bit, enough to prevent tight seal even if you apply great force by hand. For gasket and O-ring solutions check the vacuum leaks article. |
| |
| The next steps check the system under actual operation: |
- Connect 12 volts MOMENTARILY to the system - is there HHO being produced?
- Start the engine and watch the jar - are there AIR bubbles coming at the bottom of the bubbler tube? If not adjust it,
- Verify that the electrolyzer(s) produce HHO properly, and correct as necessary,
- Fill up water if necessary,
- Turn off the engine and perform a final visual inspection before closing the hood. Make sure you haven't forgotten a tool, an open connection or electrical connection.
