Recommended Posts

hi all

from my understanding the mk2 zephyr is positive earth and seeing as its all stripped

out.

i have started to put the full loom back in .

is it as easy as just chaging the earth to negitive? seeing as there is no electrics hocked up at the moment

cheers

1. Switch off ignition

2. Disconnect the battery and turn it round the other way. Cut two 'U' sections

from the metal bracket that retain the battery so it has adequate clearance from

the terminals.

3. Replace the two terminals on the battery leads (the positive and negative

terminals are different sizes). New ones are available from any good car shop.

4. Connect the earth connection to the battery negative terminal.

5. Disconnect both dynamo leads and use a long length of wire to connect the

small dynamo terminal to the battery positive for five to ten seconds. This removes

any magnetic memory that the dynamo has so it charges the correct way.

6. Re-connect the dynamo.

7. Connect the positive lead to the battery.

8 Swap the 2 small wires on the coil over. These just pull off and slide back on. If

in doubt you should end up with the black and white wire connected to the

terminal marked - or neg.

9 If the red light on the dash goes out when the engine is running all is well. If not

repeat sections five onwards.

10 If you have one of the very early cars with an ammeter you will need to reverse this

as well or it will read backwards. Some of the very early cars have heaters that run in

reverse as well but only the VERY early cars do this. The windscreen wiper motor also

runs the opposite way but this has never proved a problem.

(thanks to the mmoc)
