1450 Hydro question

[klejeune]

The OP said the PO told him there was a charging problem. So I mentioned the rectifier may be at fault there.

The no start problem may be due to a bad spark plug.

I was addressing both issues in one paragraph and should have split them up.

I agree, he needs to visually check and see if there is actually no spark.

Only getting 8 volts when cranking could be due to corrosion on the connections. Could also be a bad battery. You might take it to your parts store and have it load tested.

Have you replaced the points and cleaned the contacts yet? Also a new condensor would be a good idea and when you install that clean the mounting surfaces with a wire brush to get good ground there too. Shoot, maybe the plug wire is burnt into.

There is so much that could be at fault, but is probably just one little thing.

I as well was putting to much info into one post. I just combined the charging, no start, check valve issue all in one, I apologize for that, and for the confusion.

The 8 volts was with a battery being used to jump it with as well while being turned over, a known good battery. When it does crank it runs perfect, I will dig some more into this, and come back with more questions I'm sure. Also I will try to segregate my questions better.

The plot thickens !!! Now it runs OK as long as it cranks over OK ??? I"m glad this isn't a pilot write-up. I'd ground this plane and kick the aircrew off ! I'm going to have to offer this one over to another member ! Guys with troubleshooting problems. We can all help,,, I would think 99.5 % of the time. However we need to have very specific descriptions of the problem ! If not, we are just shooting craps !! As much as I would like to help Clint out..well... Good luck my friend. I hope you can solve your problem soon. We just are not communicating ! Probably my fault. No, most likely my fault. I hope one of the other guys can help out. Sorry ! Maybe the hydro isn't disengaged in neutral ?? That would drag the entire system down.

Hey Clint, don't get discouraged, we'll help you get it figured out. Different areas of the country have so many different meanings and not everyone knows the proper terms on how to discribe a problem or issue. Plus throw in the internet and computers and that can get folks stimied. Typing a description down and telling someone out loud are two totally different things.

When you say "when it does crank, it runs great." Do you mean the engine is running, or just the starter is spinning fast enough it should start if you had spark?

Make sure you have a good spark plug and clean all of the grounds and connections.

Sorry for the communication problems, and it was not your fault, it was mine. Instead of cranking, I should have said when it does start it runs perfect, and when it does start it will start withen 1 or 2 rounds, then the next time you go to start it you can crank it until no end, and it will not start. One time out of 10 it may start, so I may work on it an hour trying to get it to start with no luck, then say a day later it may fire right off. Sorry for the bad communication.

My 1450's condensor wire was coming loose and did something very similar. I found it when it was running and I just started wiggling wires. Pulled the wire right out of the condensor and it died. I had a good one on the shelf and it got me mowing again.

Put a new condensor on there, but make sure the ground is good for it when you do.

Good luck!

My 982 had the same exact problem. It ended up being a bad wire in the wiring harness. If you just want it to work, see if you can run a new wire from the key switch to your coil. It should temporarily fix your problem.

You might try www.partstree.com out of Austin, Tx for a view of parts and manuals. That is where I order all of my parts

Woo Hoo, Now we're getting somewhere!

Like said above, run a hot wire from somewhere... to the + (Pos) side of the coil and try to start it (providing it will crank fast enough to start) if it starts every time, then your problem is between the battery and the + coil wire end, if it continues to intermittently start then the problem is after the + coil wire end (points, condenser, plug, plug wire or coil). I don't know how to express strongly enough to make sure ALL your grounds are good, clip your test light lead onto the Pos battery terminal and touch the pointed end to the case of your coil, condenser, and then to your ground wire ends to make sure they are all good. The problem with the starter not turning the motor fast enough could be a ground problem too.

Like Sam said, now we are getting somewhere ! Intermittent problems are the worse. Run the new wire from the ignition. Everything the guys just informed you of is Dead On !
