Re: [xl7] Re: bad power supply

2006-06-14 by Aaron Eppolito

To re-secure the plug, try some JB Weld.  It's a fantastically strong
epoxy.  People repair engine blocks with it.  The "Quik" kind would be
ideal and is only about $5 for the tubes at any auto parts store.

For the leads, you might want to just heat the up with a soldering iron
and maybe even throw a little bit more solder on there.

Glad to hear it's probably not blown!
