ELT Battery Pack Meltdown

[Skywarrior]

Question for the forum -

 

What would cause a new pack of batteries for an ELT unit to 'melt'?

 

My mech recently replaced my ELT's batteries, but after a few days, he went back to it and noticed that the batteries had leaked all over the inside of the ELT, partially melting the box. Some of the fluid leaked onto the ELT's mounting tray, but did not drip onto the fuselage.

 

History: My mech had not noticed, during install, that a pin in the ELT's connector had been bent. Because of that, the ELT's Cockpit Remote switch's LED light constantly illuminated. This is why he went back to the ELT. Good thing he did, since the batteries were now toast...

 

This happened over the space of a couple of weeks.

 

Has anyone else ever had such a problem? A friend on this site tells me that this was probably caused by a short. I'd love to hear from any other folks as well...

 

 

Thanx,

Chuck M.

I would suspect a short, probably of battery voltage to ground, to cause the battery to overheat like that. I'd follow up with a call or email to the manufacturer for what they suggest next. If it is ACK technologies you'll get immediate input based on my personal experiences with them .
