[TenTec] OMNI 5 GOES DEAD ON 40

[Wade Staggs]

*O.K. I will be the first one to ask. Has nobody figured out yet where the
positive and negative battery terminals are on this RAM Chip? Maybe I have
just ask the Stupidest Question, ever ask on this forum. I have never seen
one of these RAM Chips. Can somebody please send me a picture of an example
Chip? It just seems to me that some fine wire leads and a battery holder
with the correct voltage of batteries installed, could place an end to the
whole problem. Aw Shucks, you could even install a small solar cell
illuminated from an Ironman or Batman 7 watt nightlight ..... hi .. hi ...
This is a good question ( I Hope ) Maybe the Internal Battery shorts to
Zero Ohms? So that an outboard battery won't work? *
*      As Johnny 5 Says .... Need Input !! 73 from Wade/KJ4WS*
