ELECTRICAL SYSTEM
Relays
Refer to the “ZTH electrical system” diagram.
The relays (22) plug into a holder under the
seat (on the left). The three relays are
identical and can be plugged into any of the
sockets in the holder.
Relay function (working along the holder from
right to left) is:
• Brake relay
• Run relay
• Start relay
Removing
Pull relays directly upwards. If necessary,
carefully work a screwdriver under the relay
and lever upwards.
Fitting
The relays have an asymetric pin pattern and will fit into the sockets in one way only. Press each relay down
until the body contacts the holder.
