QuickMech™ 6-Pack Relay Bypass Switch Kit — Automotive Diagnostic Tester for Fuel Pumps, Window Motors, Headlights & More (Replaces 9036, 9037, 9038)

⚡ QUICKMECH™ 6-PACK RELAY BYPASS SWITCH KIT — STOP GUESSING. START DIAGNOSING. Every mechanic knows this scenario. Customer rolls in: "My fuel pump isn't priming." You pop the underhood fuse box, stare at six identical black relays, and now what? Swap one from the wiper circuit and hope? Order a new $40 OEM relay and pray it fixes it? Or actually find the problem in 30 seconds with the right tool. The QuickMech™ Relay Bypass Switch Kit ends the guessing game. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━ Pull the suspect relay. Drop in the matching QuickMech™ bypass switch (six sizes included — one will fit). Turn the ignition to RUN. Flip the switch to ON. If the circuit works — the relay was bad. If it still doesn't — your relay is fine, and the fault is elsewhere (wiring, ground, fuse, sensor, or the component itself). Total diagnostic time: under one minute. Total parts wasted: zero. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔌 WHAT'S IN THE KIT (6 BYPASS SWITCHES) ━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ #36-SML / 10A Small Rectangular — GM, Chrysler, Japanese 1985–2008 ✅ #36-MED / 20A Square — BMW 1995–2006 ✅ #36-LRG / 20A Large Rectangular — GM, Chrysler, Japanese 1995–2007 ✅ #37-SML / 10A Small Spade — 2000+ Domestic, Korean, Japanese ✅ #37-MED / 20A Medium Spade — Domestic & Japanese 1970–2009 ✅ #37-LRG / 20A Large Spade — Volkswagen 1999–2005, Audi 2004–2006 Replaces OE# 9036, 9037, 9038 master sets. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 COMMON USE CASES ━━━━━━━━━━━━━━━━━━━━━━━━━━ - Diagnose no-start (fuel pump relay) - Test cooling fan / radiator fan relays - Confirm headlight, fog light & DRL relays - Troubleshoot power window & door lock motors - Verify horn, wiper & blower motor circuits - Quick-test starter & ignition relays before parts swap ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ BUILT TO LIVE IN YOUR DIAGNOSTIC BAG ━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ Heat-resistant thermoplastic housing ✅ Solid brass terminals — corrosion resistant, full conductivity ✅ Tactile ON/OFF rocker — no ambiguous middle positions ✅ Color-coded ratings (10A vs 20A) printed on every switch ✅ Compact enough to live in a tech apron pocket ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 WHO IT'S MADE FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━ - ASE-certified diagnostic technicians - Independent shop owners & mobile mechanics - Auto electrical specialists - Fleet maintenance crews - Serious DIYers tired of throwing parts at problems ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ THE QUICKMECHTOOLS PROMISE ━━━━━━━━━━━━━━━━━━━━━━━━━━ If this kit doesn't earn its spot in your diagnostic bag on the very first job, return it within 30 days for a full refund.
