One terminal of a double dou-ble contact Indicator bulb on the dash should be connected with the current supply and the other terminal with the wire that makes contact with the float disk. If the cap unscrews arrange ar-range the contact wire so that It can be swung out of the way. If the cap turns back on a hinge the contact can I be fastened to a piece of fiber or bake-II bake-II te and connected by a piece of flexible flex-ible wire. Popular Science Monthly. |
