Inside the Wiper Motor: Contacts

[Larry & Nancy Solheim]

She's cleaned-up, greased-up & back together, but
continues to exhibit the "intermittant stop" problem.
I think I've narrowed it down to the relay contacts
under the light aluminum shield over the electrical
connections.

Question: Just how should these sit in power off
condition & what is their movement in normal operation
when power is applied? I lightly filed the contacts
and now have continuous operation w/ switch on and a
hickup (slight stop) before the motor keeps on running
when the switch is turned off. I figure I moved
something, but at least have found an area of attack.


It appears
--31 is case ground
--53a is fixed contact
--31b is short flex arm (not touching anything at
present
--53 is long flex arm which is resting against the
fixed contact.

Thanks,
--LarryS

With a dash of common sense and an EXCELLENT wiper motor disertation
on the Vintage Triumph Register (www.vtr.org) I managed to solve my
own problem.

The maintenance section of vtr has many more articles (ignition,
carburation, much more) that could be of use to the aspiring Amphicar
mechanic!
