Does anyone know someone who can repair this tester ? It does not test condensers . Reason is bought a battery from Battery plus bulbs and the top plate from factory duracell 903 . Positive and negative were reversed from factory . I called Arthur at mercotronic they have parts but don't service these testers . I am trying to get duracell to pay for repair they are going to have corporate call me . Any help would be appreciated ! My name is Jeff & phone number is 414-708-5784 or email email@example.com .
Went to post pictures & you email address doesn't seem to work. So the most likely part that's faulty will be the NE555 IC, check P8 on the IC it should have +5v DC on it, if it does then replace it they are cheep about $1 ea.
I'm not a member so that could be why . I'm not good at electronics repair , that's why I'm asking for repair help. Mechanics is easy for me . Email is firstname.lastname@example.org or phone 414-708-5784 . I would really appreciate the help .

Hi Jeff have sent an email with pictures, apears to be successful this time. Incidently I am in Australia. Forgot to mention in the email the picture with the 555ic pin 8 is at the point of the biro to measure for the 5v.
Debe, Triple 5 timer is one of the oldest chips around sept the 556. Jeferyward, I can send a diagram of the 555 if you want. Need a solder sucker & low temp pencil & it's easy. Look for the notch & replace in the same direction.
