Jeep CJ-7 Jump Post Location & Safe Protocol

📍 Step 1: Terminal Location

Battery & Remote Jump Posts

Jeep Grand Cherokee (WK2/WL): Main AGM + Aux battery are under the front passenger seat—always jump via the under-hood brass (+) post and negative (-) ground stud! Jeep Wrangler JL & Gladiator JT: Engine bay main AGM battery (with secondary ESS AUX14 battery underneath the fuse box).

⚠️ Step 2: ECU & Fuse Safety

IBS & Fusible Link Protection

2018–2026 Jeep Wrangler JL, Gladiator, and Grand Cherokee models have a small secondary ESS (Electronic Start/Stop) AUX14 battery and a high-current N1/N2 Z-Case fuse array. When the small Aux battery fails, it drains the main battery and blows the N3 fuse if jumped improperly.

⚡ Step 3: Charging Check

Alternator Voltage Test

Post-boost verification of 160A–240A Denso Alternator + 48V eTorque output (13.8V–14.8V on 12V; 27.6V–28.4V on 24V commercial).
