electrical modifications: conversion to a 5 spd ecm/harness and battery relocation to the trunk.
car was like this when i bought it.
symptoms: major symptom is stalling when stopping and clutch is pushed in.
condition: intermittent
observation: usually only does this when under electrical load, sometimes when the headlights are on and almost always when i use the turn signal.
other observations: turning on major electrical devices can cause change in idle but for some reason the signal lights have the most profound effect. also the turn signal drives the speedo crazy but has no visible effect on the HUD speedometer. tach cannot seem to accurately monitor the engine rpm at high rpms and also charge indicator will start to flash.
other observation: cannot cause stall while in idle and when in gear(clutch pushed in) stall is a little harder to cause when cold.
voltage: 12.05-12.3 at idle from the cigarette lighter. when all devices are on, lowest observed voltage is 10.03(idle is crappy then) but usually will climb up to about 11.13 with everything on.
ground resistence: 3.5 ohms from ign module ground to neg battery terminal. i haven't tested the ecm ground resistence yet.
other observations: the previous owner just hooked the ground to the body in the trunk.
my list of possible culprits include. alternator, improper grounding, improper integration of different harness(be it ground or power).
what i have done so far: ran a small guage wire from ign module ground to the negative terminal, no change in condition. also cleaned the ground connection up and replaced the self tapping fastener with a nut and bolt to tighten it up real good.
any suggestions on things i can do to help asess the problem or any possible culprit suggestions would be appreciated. thanx.
