Starter Solenoid for Delco 42MT Series Starters
24 Volt · 4-Terminal · Insulated Base
This 24-volt starter solenoid is an aftermarket unit built to Delco 42MT OEM specifications. It uses copper wire coils wrapped around a moving core that magnetises the moment the ignition is engaged, pulling the starter drive gear into mesh so the engine can crank.
Fitted with an insulated base and four dedicated terminals (Battery, Motor, Switch and Ground), it is a direct replacement for the Delco 1115595, 1115601, 1115608, D901A and D912A solenoids fitted to 42MT series starter motors across marine, agricultural and industrial applications.

Frequently Asked Questions
Will this solenoid fit my starter without modification?
Yes, it is built as a direct, bolt-on replacement for Delco 42MT starters using the OEM numbers listed above - no modification is needed.
What is included?
One 24V, 4-terminal starter solenoid with insulated base, ready to fit.
How can I tell my existing solenoid has failed?
Common symptoms include a single loud click with no cranking, an intermittent or completely dead start, or a starter that spins freely without engaging the flywheel.
Is this compatible with 12 volt systems?
No - this is a 24 volt solenoid only. Fitting it to a 12 volt system will prevent correct operation.
