It has gone to full scale reading, and will not respond to either earthing or higher ohms at the input. The sender is working OK. I'm assuming the gauge has gone u/s ?

LOL From: "checkn6" I have been searching the archives for days and just short of reading every post I cant seem to find what I was looking for, drats! Some time ago I recall a post from someone that Bob had answered with a link to a product that he found on Ebay, now that I really need it, can I find that link? Grrrrrr. LOL Someone had drawn a simple and rudimentary schematic and it goes something like this, 110 AC from a house circuit then to a control box (having a senior moment and cant for the life of me think of what this box is called) that routes a charging/maintaining current to a battery(s) and also provided 12V DC to an external device, then if the AC was removed the box would automatically provide power from the battery to the 12V circuit. I remember that it was a hardwired device and not just a simple plug this into that type of set up. OK, this is one of those moments where you try and try to think of some ones name that you know well but just cant get it out. As soon as Bob chimes in a says oh yeah, it was a X control box and here is the link it will all come rushing back and I will be embarrassed once again because it is so simple. I hate embarrassing myself but oh well. LOL Thanks for putting up with me wasting your time this morning.

No problem Chris . . . sorry that you felt a duty to be so diligent in the self directed search. One of the major assets embodied in the List is a broad spectrum of random access to data. I don't recall the exchanges you're citing but it sounds like you've got a 12v device that needs un-interruptible power? How much power does the device need, how long do you need to support the device in case of power failure? How big is your battery? There are a number of power supplies that could be combined with a relay or perhaps a diode to effect the changeover. If we had more details on your mission, perhaps an elegant solution is readily at hand.

I through the engine was overheating, but have learned that the EFIS/EMS is showing the readings at 36 C hotter than the K type probe I used to check the cylinder head temps vis the EFIS readings. It takes a few minutes to remove the cowling then the plenum chambers. The temps drop to about 110-130 C according to the K type probe, but the EFIS shows then to be hotter. I have checked the K type in ice and boiling water and it is right on. The CHT probes show normal temps, but as soon as heat is applied they start drifting towards the hot side. I'm not sure what to do. The CHT probe are K type probe with a solid wire extension to the EMS unit. The EMS unit is grounded to the engine block. Any ideals would be a big help.
