OEX Starter Motor Slave Solenoid 12V ACX3342

The OEX Starter Motor Slave Solenoid is a 12V solenoid identified by part number ACX3342. It is supplied as an each item and is listed as a starter motor slave type, making it a specialised electrical switching component rather than a general-purpose relay or breaker.

This unit is rated at 150 Amp and is designed for intermittent duty. It is fitted with an ignition ballast terminal and is noted for firewall mounting, which are important details to confirm before ordering if you are replacing an existing Lucas-style or universal application solenoid.

At 0.46kg, the solenoid is a compact electrical part, but correct identification still matters. Matching the 12V requirement, the ACX3342 part number, and the terminal arrangement is the safest way to avoid buying the wrong component for the application.

Application and Buying Notes

Start with the basics: this is a 12V starter motor slave solenoid rated at 150 Amp, so it needs to suit a 12V electrical system and an intermittent duty starting circuit. If the original unit is not a Lucas-style or universal application solenoid, compare the existing part carefully before purchasing.

The ignition ballast terminal is a useful identifying feature, but it also means the terminal layout needs to be checked against the vehicle or equipment already in service. A mismatch here can make installation difficult even if the unit appears similar externally. Part number ACX3342 should be used as the main reference when cross-checking.

Firewall mounting is another practical point to confirm. The mounting position, bracket arrangement, and cable path should all be checked against the replacement location, especially when working on older or mixed-application electrical systems. The weight of 0.46kg gives a general sense of the unit size, but the terminal and mounting details are the real compatibility checks.

For buyers comparing options, the most important details are the 12V rating, 150 Amp capacity, intermittent duty specification, and the fitted ignition ballast terminal. Those details tell you what the solenoid is intended to do and help reduce the risk of choosing a part that looks similar but is electrically different. If you are replacing a failed unit, comparing the old part number, terminal count, and mounting style will usually give the clearest result.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number ACX3342 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Starter Motor Slave Solenoid 12V. Part number ACX3342 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX3342, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a solenoid in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm fitment by matching part number ACX3342, the 12V system requirement, the ignition ballast terminal, and the firewall mounting arrangement before ordering.
