Maintenance is essential to prevent your EMM from breaking (again). Here are some simple steps you can take to maintain your EMM:

1. Ensure your battery connections are securely fastened. Loose connections can cause power interruptions and generate high inductive spikes that may damage the ECU.
2. Inspect your battery terminals and cables for corrosion. Corrosion can disrupt electrical flow and pose a risk to the EMM.
3. Check the condition of your battery switch. A faulty switch can lead to power interruptions, endangering the EMM.
4. Properly connect high-power consumption devices like radios, fridges, or inverters. Poor connections can disrupt the charging circuit, potentially damaging the EMM.
5. Monitor EMM cooling across various RPM ranges. Efficient cooling is crucial for the EMM's lifespan, and water flow may differ at different RPMs.
6. Examine the connectors leading to the EMM for signs of corrosion.
7. Inspect the connectors on the EMM itself.
