Posted: Sat May 09, 2015 11:15 am Post subject: Rotax 582 voltage regulator

I recently (a few months ago) installed a lithium battery in my Pulsar.  It is a lot smaller and lighter and seems to have a lot of cranking power.  Today on a short 0.5 Hr flight my panel went blank except for my Garmin 286 which has a back up battery.  This happened when I reduced power on final.  I have had the panel go dark a couple of times before when I shut the engine off.  That was a nuisance but did not like losing it on final!  After shutdown I removed the cowling but could not find any problem.  Reinstalled the cowling. The battery was showing 12 .9 v on the EIS.  I started the engine and returned directly home, a 0.3 hr flight.  Lost power briefly when I shut down at my home hanger.  On the way home so saw 16.7 v on the EIS.  CLEARLY TOO HIGH.  I suspect I have a voltage regulator issue, or a bad interaction between the regulator and the battery.  Any troubleshooting suggestions?  Any way to bench test the regulator?

Speaking of batteries, I have a new, unopened Odyssey PC680 that I could bring to Lawrence if anyone would like to have it for $80.



Interesting that Rotax says not to use a lithium battery in the 912iS installation.

I have an unused 582 regulator pay the freight and you can have it !

That symptom does not lead me to the regulator. Loss of  power, if a complete loss is something in the path from the battery is failing.  Two reasons/symptoms. A high voltage reading on the EIS indicates there is no  load on the regulator. That is it is not seeing the battery. And the second  symptom of your dash going dead also leads to a bad path.

  

 A simple loose connection would be my first suspect. If  you have a relay in the path between the battery and dash it could be failing or  have a loose connection. 

  

 In any case this is why my radio and gps's units had  battery backup. 

  

 If you have a schematic of your system it should be easy  to come up with the most likely fault point. 

  

 One trick to try to sort it out is to gently touch, tug,  and tap around to try to duplicate the dead panel issue. Be very gentle. If it  is a loose connection and some corrosion has developed then touching a loose  wire can temporarily cure the problem. 

  

 On the good side, if there was enough power to turn over  the engine it is highly unlikely the battery is defective.

As far as I know, lithium batteries have different charging

requirements than lead batteries. Just swapping the batteries without

adapting the way it needs to be charged may lead to a short life of

the lithium battery. That may be why Rotax does not want the use of

that battery for their engine.

For my electric tricycle, which has a lithium battery, I have a

special charger that is just for this battery.



Anyone out there with more knowledge about this issue?

Any lithium batteries have very different charge requirements to lead acid type batteries. 

You definitely need a special charger and generally these will individually charge or 'balance' each cell, as well as cater for the different voltages etc. I would think that any manufacturers would strongly recommend against straight swapping lead acid for lipo batteries for very justified safety reasons.

I'm sure if you Google it you'll have enough material to read for days on why this should not be done.
