Up for sale are two Sun tachometer transmitters, one 8 cylinder and one 6 cylinder (1) Model EB-7A / 12volt / 6 cylinder (1) Model EB-9A /12 volt / 8 cylinder SOLD !!! I took the covers off both and took photos, the battery contacts seem to be in good shape on both. I've no idea if these will work with new batteries or the working condition of them. I am selling these as a restoration/ parts units. Shipping is extra and thanks for looking.
