 |
|
Hi all,
since I'm planning to move (the much lighter) LiFePo battery
http://www.accu-24.de/ALIANT-LiFePO4-Ultralight-Battery-X4-13-2-V-92-Ah from the baggage compartment onto the right footwell and having to change the Rotax sprug clutch this winter (lots of kick backs on starting), I'm also thinking about installing a heavy duty starter like this one http://silent-hektik.com/UL_912_Anlasser.htm .
I seem to remember, that it's most advisable to retrofit it on the 912 S with its higher compression.
Did anyone of you install such a heavy duty starter on the 912 or 914 or is it just overkill for this engine?
Regards
Roland

Hi Roland.
Get the Soft start model, from Con Air.
Problem solved.

Hi Alan,
I watched the Bully Hawk Video - also a good idea to cure the kick back, but one also needs to deactivate one ignition circuit on starting to get the best results.
I'll also consider this - thanks.
Regards

Hi, Roland.
I take it you have a Key ignition switch and not two separate on and off switches.
If so you can still use the same switch as L and R mag, and Both.
All you need do is deactivate the starter position and take those wires to a separate Starter Button.
Job Done.
The Soft Start then takes about 20 minutes to fit.
Its an easy job to do.

Or you can disable the hard start module by routing it through a switch
you'll keep off when you start. In my case it was avionics power, which
I don't switch on until after start. Once started I switch on the
avionics, which also activates my B, non soft start, module. That
allowed me to use my existing key switch as before. It also allows me to
kill the B module before I shut down, which helps as well.

So does that mean if you switch off the avionics master because you have an
electrical fault that you lose one of your ignition systems? Hm...

Yes it does, but my avionics are simple in the extreme and very unlikely
to catch fire. Any shorts should be handled by the fuses. Not optimal, I
know, but best I could do without a major rework. (The install was a
retrofit.)

This starter is longer and depending on your engine mounts may be too long.
Some who have used after market starters have had oil leak back into them due to bad seals.
