Wipers - What Rectifier Diode Should I use?
Not using a "special" wiper switch and want to use a push to break relay to disable the park switch connection to the low speed terminal
when wipers are switched on.
This will obviously mean that I either need to use 2 relays, find a push to break relay that has 2 trigger terminals or connect both fast and slow
feeds to the terminals with a diode to prevent back-feeding the other speed.
a) Can anyone see a problem with this?
b) Any recommendations on a suitable rectifier diode that's easily available from Maplin (got a Maplin round the corner but no RS Trade
Counter)?
c) anyone got a better solution? Only available connections from the car loom are: fast +12v, slow +12v, ignition +12v, earth.
Thx
Stephen
