Dead Accumate?

[scruggs]

Just in case I am missing something simple ......

Plug in the mains and the red light comes on but nothing else, no charging or fully charged light.

It has been professionally wired in some time its history so I traced the line to the battery in the footwell. The 20a fuse is intact.

There is one connector in the line. Pulled that apart and put a meter on it.......nothing, not a single volt or wiggly amp in sight.

I guess the transformer (if that is what they are called these days, I am a product of the 50's) in the Accumate has failed.

Think I might buy myself something that plugs into the cigar lighter socket to charge the battery, I have had enough of kneeling in the slush for one winter.

It would do this if you had disconnected one of the battery terminals.

I have just gone for a connector off the battery as the lighter connection was becoming unreliable.
Once you've got the fused connector in from the battery (was that a fuse in the connector that you checked?), run an extension cable under the carpet and up behind the passneger seat and then poke it out of the bottom of the rear screen just behind the door whan you want to charge it (or poke the charger cable in through the same orifice) - no slushy knees.

Accumate can check it over for you and repair if required - I enquired in case it was my charger and not the connector.
IIRC it's free except for postage.

So the Accumate will not produce any charge if a complete circuit to the battery and return is not present? I connected a meter between the output of the Accumate and an earth point on the vehicle and registered nothing.

I have a new CTEK on the way to charge the Chim and will take out the old Accumate and test it before using it, if serviceable, on another vehicle.

Thanks for the input (excuse the pun) guys.

Don't know but when I had the earth disconnected the same as you have happened and I thought it was knackered. Connected the earth (after finally realising it wasn't on) and it worked as normal.

"If" the charger is smart enough to turn its output off when it detects and open circuit, then just put a small load across the connection, such as a small 12 volt bulb (not an LED, but filiment lamp) and see what happens. Id be surprised if it does switch off however, as a badly sulphated battery is almost open circuit, and with no voltage you dont stand a chance of getting the current flowing to start the charging cycle.
