I think I'll stick with the electrician\controls engineering route, ride systems can be annoying enough yet gratifying

I had one blow in an old tv set and it created a weird oscillation the image looked like a twisting helix. I was so upset as it happened when i had made it to a level in a video game I had never reached before.

having a single phase outlet on 3 phase is extremely common. converting a 3 phase head to single only requires some rewiring, problem is not all heads are externally tapped for it

I once was asked to proofread a tech manual for a ride, I found several errors in the general prefave section (where all the safety info etc lives). I caused the recall of every manual the mouse wrote between 1989 and 2013

Probably for the best. Let me know how I can help, or if you guys can get me known errors I can start editing

That might be a fun project to take on.

You're welcome

Have you by chance checked the valve lash?

A great degunk and lacquer remover is Chem dip. However know what you are doing because its a bit like going after a fly with a bazooka. Last time i used it was on a 003 IP (same as the 002) and check valve. BUT the IP was completely rebuilt after. It was very clean once removed...

Agreed, But every safety rule and building code is written in blood so someone did, there was probably an injury or property damage, now there is another code to learn.

In the normal configuration, you can pull a breaker and the buss remains live and the breaker doesnt. When backfed breakers (especially QO) have live bits sticking out and able to hit things.

NFPA 70 408.36 (D) if youre curious.

If you are back feeding a breaker for the main you either need a bolted in breaker or some other form of Anchorage to the bus bar you cannot rely on a snap and breaker to be a back fed main Just one of those code got you FYI things

Under voltage light or is the voltage actually low?

2 check valves per pump, normally they are blow through so a weak pump shouldnt cause a stall, there is also one in line between the filter and IP. its in the hose right by the oil pressure gauge. Not on this series of set but i did have another piece of equipment where a check valve...

Hey now, not only am i going for removal, I am also trying to break a distance record

To me it sounds of starving of fuel

Yes thats the point. The slug seizes up, when the pump is disassembled (except the slug) compressed air in the output can be used to dislodge the slug if a solvent and tapping doesnt work. I have only had a pump badly gummed up once to need to blow it apart.

Knocker loose works wonders. Also compressed air through the outlet can pop it loose
