His diesel truck has TWO 12V batteries but they are connected in parallel for use by the truck for starting, etc. The solenoid requires right at 1 A @ 24VDC. Would it be possible to connect another small set of wires in series on the batteries to get 24VDC for the solenoid? I wouldn't think so, but I did not know if you used diodes if that would allow it to work. If not would you have to use a 12VDC -> 24VDC transformer? thanks. mattmc [/quote]    Insert an Image File (GIF, JPG, JPEG, BMP, ZIP, PNG) Check here to include your profile signature.
