I recently obtained a 35ES which is in good condition except for one thing. On fitting a battery, the meter did nothing. Opening it up revealed some corrosion on the rear of the battery compartment contact. I removed this, pulled off the wire and pressed the battery against that, and the meter fired up fine.
The terminal on the battery compartment therefore needs repair or replacement. Can anyone recommend either (a) a suitable cleaning substance, (b) if there are any cameras other than the ES/EE and its known clones which might act as donors for a suitable replacement, or (c) whether there are any other sources of replacements (including bodging something from other materials - though I have limited tools). It's a cup-shaped thing with two small screw holes and a terminal at its centre.
Naturally, this post also serves as a kind of underhand plea to anyone who may have a spare one of these in a dusty pile of parts somewhere ;) |

Kill the corrosion by giving the contact a good soak/brush up in an acidic toilet cleaner, then polish up the contact using a medium grade emery paper. Remake the electrical connection properly and you should find all is OK. It is quite rare to find that a contact is beyond redemption - unless the whole battery compartment is jam packed with a corroding/oozing battery and even then the patient can sometimes be revived with a little elbow grease! |

Thanks, I will have a go. I may have to be quite covert about investigating bathroom cleaning products in order to avoid some pointed comments about never having previously ventured near them  |

I have used distilled white vinegar with success in cleaning battery contacts with leakage damage.
