<SNIP> When ideling, with A/C on, my car blows cold, BUT the voltage DROPS down to about 9 volts </SNIP> This could be any of a number of problems, but assuming that your voltmeter is working reasonable well... I would do the following. Check to see if having the blower on high and putting your high-beams on makes as big a difference in the displayed voltage as having the A/C on with the heater fan on low. If everything makes the voltage drop significantly, check the battery and dash grounds for corrosion and tightness. You can also have the battery and alternator checked out the results can be misleading if there are other problems. If the Radiator A/C fans are the biggest problem, check that they rotate freely. Be careful that they don't come on while checking them. Check their connections and grounds. <SNIP> My fan kicks on and off every 5 seconds! </SNIP> If the A/C compressor clutch is also cycling on and off at the same rate, this could be marginally OK. You may need slightly more Freon charge. Cycling every 7 to 10 seconds is considered "normal" for a DeLorean. If the fans are cycling while the A/C compressor clutch is still engaged, the circuit breaker might be part of the cycling problem, which leads you back to troubleshooting why the fans are drawing so much current. Last week we discussed cleaning up and/or upgrading the relays and circuit breakers, but you need to find the problems first, not cover them up. Gary www.IN2TIME.com
