Evening. 
 

Looking for help On the diode. I did find a PN but nothing is coming up on the inter webs. Has anybody found a substitute?

 

PN 10h3n

Lasar is probably the best resource to go through

 

Are you just looking to replace a burned out one?
 

Are you familiar with how it got killed?

The internet said it was in here...

Lots of pages to go through if it isn’t... this site belongs to an MSer.

Best regards,

That particular diode is not manufactured any longer, the company Sarkes Tarzian went out of business many years ago. M20J uses a 10H3P part number NTE5854 or ECG5854 for the same circuit.  They show the 10HP3 on the LASAR website but are currently out of them. I was able to pick one up on Ebay for my F.

While on the subject of ground power, I connect my three pin jumper cable to a Sears battery charger to power up the system when working with the avionics.

There is a toggle switch on the charger for various AMP settings, and my question is, what is the maximum that I should select? In other words, how much will she take?

Assuming your charger’s voltage is correct, the battery will accept only the correct charging current, assuming the battery is fully charged and your using say 10 amps then the system will only use or accept 10 amps, even if you have a 100 amp charge source.

‘This is exactly what happens with say a stock 60 amp alternator, if the battery is at a low charge initially the current will be high, but once it’s charged then the system only accepts what’s used.

‘Sometimes though cheap chargers don’t control voltage very precisely. and they can overcharge a battery because they are supplying too high of a voltage.

‘You have a volt meter in the airplane, so that’s easily checked, I’d not use that charger if you see 15V or higher.

‘I would set the charger for its highest amp selection
