4.6. FLOW CONTROL VALVE
Prior to each day’s spraying, the flow control valve should be inspected to ensure there are no leaks around the attach-
ment fittings. At the end of the day, care should be taken to thoroughly flush the flow control valve with clean water.
4.7. WIRING HARNESS
Most failures of electronic systems like the TASC are the result of broken wires or poor connections. Taking some time
to periodically inspect and clean the wiring harness will help prevent this type of failure.
Inspect the external cabling for abrasion, stretched or pinched wires. If damage is seen, reroute the cabling and wrap it to
protect it from further damage. If a broken wire is found, it can be temporarily repaired by stripping the wire back on
each side of the break, twisting it together and SOLDERING the connection' (Do not use acid core solder). The bare
connection must be well insulated with heat shrink material or electrical tape.
MID-TECH strongly recommends replacement of damaged cables as soon as possible. Once the cable insulation is
damaged, moisture and chemicals can work their way under the insulation and cause corrosion to the conductor. In the
end, continued problems will be experienced with the cable if it isn’t replaced.
The connectors at the ends of the cables must be periodically inspected and cleaned. Use a non-lubricating spray solvent
(such as a tuner cleaner) to clean the connections. Lubricating sprays leave a film which collects dirt and can eventually
lead to failure of the contact. If the contact is so dirty it must be wiped clean, use a non abrasive swab (like a Q-TIP),
along with the solvent, to avoid wear to the connector contact.
Sometimes connectors become damaged or worn out from many years of service. In this case, contact your MID-TECH
supplier for a replacement connector kit.
