Posted: Fri Aug 21, 2009 5:17 pm Post subject: Jump Starting? - Solution

Just thought I'd update anyone who followed the thread - and those who responded directly.

  

 First; Thanks to all who took the time to share their solutions or opinions. I read and carefully considered each of them. 

  

 I take the idea of "experimental" more literally than some - so this may not be my ultimate solution; but it's my current one. My "design criteria" for a jump start are 1) safe 2) rreasonably easy 3) low parts cost and 4) low demand on the local FBO (if there is one). Number 4 probably drove my solution more than anything - as many of my destinations are Very Small airports with little or no FBO support. I can typically get into town from the airport - but if I break down, it's up to me to get going again. So I decided against any unique "plug" and will simply rely on getting access to normal car jumper cables. 

   

 Therefore my solution was to route a 2AWG wire from the positive battery terminal along the top of the motor mount, terminating close to the oil access door. I chose the positive battery terminal over the master solenoid only because it was easier (and in my opinion, safer) routing. I had a leftover 2AWG wire out of Vans wiring package that was insulated & had lugs on both ends so I used that. I attached the wire to the motor mount at 4 points. Each point used 2 cushioned Adel clamps; one around the motor mount and the other around the wire. 

   

 I put 2 layers of corrugated wire loom around the already insulated wire to protect it against a stray wrench/screw driver. To protect the lug at the oil-door, I tie wrapped a leftover auto-spark plug boot and 2 layers of corrugated wire loom. ( tho tie wrapping may be overkill, I don't expect to use it frequently and also didn't want the boot to accidentally vibrate out). I also put wire loom around surrounding motor mount pipes in case the jumper cable clamp slips.

   

 Now jumping my airplane should be easy. All I need is some borrowed/purchased auto jumper cables and a battery (airport car, another airplane, etc.). Just cutoff the tie wraps around the spark plug boot and connect the jumpers thru the oil access door; negative to the motor mount bolt and the positive to the exposed lug. Once it's started, put the boot back onto the lug and fly home. 

   

 If the description doesn't make sense, just drop me a note and I'll send you pics.

I did the same thing ,but I used a 3in piece of pvc just large enough to fit over the lug. Drilled a hole in the pvc and put a tywrap thru the hole and the lug. To use, just snip the tywrap , slide the pvc down the cable and attach the jumper cables as you suggest.

So now that that is settled...  perhaps now it's appropriate  to discuss the wisdom or not of jumping into and immediately flying off  in an airplane that is still trying to charge its (still dead)  battery. ;o)

I wonder how much safer that method is, trying to put the boot back on 

and make sure it is tie wrapped

so the lug well not short out while standing a few inches from a 

spinning prop.
