Leaking alkaline batteries, the bane of our portable, battery powered existence. All too many times I have found myself repairing electronic devices damage by leaking batteries, or just junking the gear when the damage is too severe.<\/p>\n\n\n

The Celestron designers, in their infinite wisdom, decide to locate the battery compartment above the main cicuit boards. This on a device that will often spend time in storage between uses and leakage is likely. The result was predictable.<\/p>\n\n\n

This particular telescope was handed off to me as an inoperable case. Nearly worthless except to part out unless you have the skills to fix it. <\/p>\n\n\n\n

The corrosive battery electrolyte dropped onto the circuit boards below, corroding traces and worse, getting into the connectors. The result was a the green growth seen in the photos here, green from the copper dissolved away from the circuit board traces and wires where it belongs. <\/p>\n\n\n

The saving part of this incident is that the circuit boards are available at reasonable cost. If you consider about $120 reasonable for the set of boards. The connectors are also standard parts, available from the usual electronics suppliers.<\/p>\n\n\n\n

Thus an evening of work restores this telescope to running order… The boards are easy, just a few screws to bolt them into place. The connectors are another matter, a couple hours of painstaking crimping contacts to wires in order to replace each of the connectors.<\/p>\n","protected":false},"excerpt":{"rendered":"
