I have a Slickstart start unit. Manual calls for a 5 amp fuse but my fuse blows at 5 and 7.5 amp, I have a 12V installation.

 

Have now installed a 10 amp fuse and all seems to be OK

 

What could cause the Slickstart to draw more current?

 

Should I be concerned?

 

Thanks

 

Mike

That seems odd.Â  Mine runs off a 3 amp fuse, including the start relay.



There was a bulletin some time back to only run one mag with it.Â  I think it had to do with making sure the left and right systems were completely separate, not really a current draw issue.Â  Maybe though...are you running both mags off a single SlickStart?

No, I am only connected to the left mag. Right mag is switched off during engine start.

 

Thanks

  Is this a new installation or does it have

  a service record on this airplane? Excerpt

  from installation manual:



 SlickSTART receives input power from the switched positive terminal of the starter motor,

 and should be activated only when the starter motor is engaged.  During engine

 start, SlickSTART draws a maximum of 5 amperes at 6 to 25 volts (P/N SS1001)

 and delivers a series of fast rising 375 volt maximum pulses to the primary

 of the magneto coil.  This voltage is stepped up in the secondary of the coil,

 and is impressed across the spark plug electrodes through the magneto distributor

 and the high voltage harness. 



   I think there's something seriously amiss . . .

This is a new installation,  it is a P/N SS1001 as per the manual. I bought the unit unused from a person that  had it on the shelf for more than 15 years, don’t know if that will make a difference. Came in original packing with manual etc. and I don’t think it has been connected peviously.  

 

It is connected to the left magneto on a LOM engine, it is powered directly from the starter solenoid.

 

I powered the unit directly from the battery, removed the plugs and rotated the engine by hand and it supplied a vey intense spark.

 

Hope this helps

 

Thanks

This may be a duplicate, I sent it this morning but did not see it in my inbox  This follows on my previous submission where my SlickStart is blowing 7.5amp fuse.

 

This is a new installation, it is a P/N SS1001 as per the manual. I bought the unit unused from a person that had it on the shelf for more than 15 years, don’t know if that will make a difference. Came in original packing with manual etc. and I don’t think it has been connected previously.  

 

It is connected to the left magneto on a LOM engine, it is powered directly from the starter solenoid.

 

I powered the unit directly from the battery, removed the plugs and rotated the engine by hand and it supplied a vey intense spark.

 

Hope this helps

 

Thanks
