Service Manual for SPICE series? (Dead 34C) (Repaired)

[jebem]

If you search for hp spice repair here in the museum you should find some information.

The flex power cable is known to fail due to a number of reasons.
1. Battery leakage is the most common reason.
2. However the flex cable connection to the battery holder contacts can present high resistance due to aging (oxidation, dry electrolysis, you name it). Hp used metallic rivets as contacts, no soldering involved here, so we have two different metals pressed one against another.

I had the issue number two above on my Spice calculator.
Have used a ohmmeter to check the continuity and one of the battery contacts had high resistance (we need zero ohms here).

This is my 32e repair report:

Good luck with your repair.
