FEDERAL LAW
183.440 - Secondary Circuits
of Ignition Systems
(a) Each conductor in a secondary
circuit of an ignition system must meet SAE Standard
J557.
(b) The connection of each ignition conductor
to a spark plug, coil, or distributor must have a tight
fitting cap, boot, or nipple. |
Conductors in secondary circuits of ignition
systems consist of the conductor from the center tap on the
ignition coil to the center or rotor terminal on the distributor
cap and the spark plug wires. These conductors must meet the
specialized requirements of SAE J557 “High Tension Ignition
Cable”. Both ends of these conductors must be connected
in such a manner as to be protected by a tight fitting cap,
boot or nipple. Caps, boots and nipples that meet test requirements
incorporated in SAE J1191, “High Tension Ignition Cable
Assemblies”, are acceptable.
TO COMPLY WITH THE LAW
- Does each secondary circuit conductor
meet the requirements of SAE Standard J557?
- Are all connected ends of secondary
circuit conductors equipped with tight fitting caps,
boots or nipples?
