Hi everyone!, Hey I'm having a small but irritating problem with my
electrical on my 1993 OMC Sunbird.
The problem is that sometimes the engine doesn't start right away and
requires a few more cranks by the starter to get it going. I'm talking
about a 3 - 4 second crank time altogether before it starts. When the
cranking hits the 4 second mark it seems I lose power briefly to my fish
locator and stereo. If the engine manages to start in the 2 - 3 second
time frame this doesn't happen. I have load banked my battery and it
tests really well. I have the locator and stereo connected to my
accessories dash rocker switch.
Is there a quick fix for this besides installing a second batery?
Do I need to install a diode in the accessory circuit to prevent the
started from sucking power back from the locator and stereo?
Thanks. Chris

Ignore the electronics drop-out. The system voltage during cranking is
dropping below the minimum req to run the electronics. It's not a
related fault.
