Title: Onan Electric Plant 5.0 CCK-3
Post by: Jolly on February 22, 2013, 02:45:05 AM
Back when I was checking out this truck I just bought, I had the seller sending me Photos, I seen a photo of the center of the dash and there is this switch labled Generator, Start, Stop, so I ask if there is a Generator on the truck, the sell replyed back he didn't know if there was, but he would check. He sent me a photo of the Onan Electric Plant, I guess he never looked in the compartment  on the truck, so he didn't knoe this was even on the truck. That was one of the first things I did was to open all the campartments and see what if anthing was there. That when I found the Power reel with what looks like hundreds of feet of power cord, they never sent me a photo of that either. I asked for photos inside all the campartments, and they sent me photos of just the driver side, and ofcourse the Generator of power reel are both on the passenger side.

I wonder what the 'rotary-dial' device is on top of the dash...probably prior to MDT's, or to call the hospital, etc.?  Cool.. :-)

Those rotary pulse dialers were an early select call system used mostly so hospital er's didnt have to listen to radio traffic not intended for them.  Also used in some areas to contact regional or neighboring dispatch centers/

Referred to as Secode I believe. A very distinctive sound on the radio when someone was dialing. The Mid-State Fire Mutual Aid System in central Massachusetts used Secode well into the 1990's. Everyday when it was time for the system radio test a single code was dialed and it opened the recievers in all the dispatch centers.

The hospital system was called HEAR, based on the 155.430 vhf channel was in common use here in the south well into the late 90's but since then almost everyone has switched to either cell phones or a dedicated trunking group.  Up unitl at least 2000 Kentucky law required all ambulances to be equipped with the system even if it wasnt used in their region.

Thanks for the info. on 'the system'.  I found THIS which explains the program in detail, for folks like me who have forgotten or didn't know.  :-)
