Re: '90 Bluebird having wierd problems suddenly by gw
Post New Message May or may not help you.not familiar with your ride but may point something to look at.
1) "Low vacuum" light and buzzer came on and won't go off. (Fact: it has hydraulic brakes; I have no idea about anything vacuum related).
i also see you said you added diesel, so i assume its a diesel engine your talking about. since you have juice brakes and not air, the brake system needs a vacume or hyd.pump to assist you in appling the brakes. the light/buzzer your refuring to is more than likely to be related to an eletrical prob.. (will prob. be fine once you take care of other issuses.
2) Engine dies when warmed up. I added a couple gallons diesel even though guage says 1/4 full. Won't start at all now.
the reason the engine prob. died was(again dont know what engine you have) but sounds as though your volts dropped to a level that they could not maintain the voltage require to hold the fuel solenoid open.(this to will be ok once electrical prob. is fixed)

3) Ammeter reading low (like about 9 volts when running; maybe alternator is going out). Strange electrical things even with not running: such as turn on one set of lights and then the instrument lights come on. Or when running, turn on headlights, and the "low vacuum" buzzer grows faint for a few moments.
before you start tearing into things. i would suggest you remove the batteries/recharge then test them. cell test,load test,volt test.. then (again not knowing the system) whether they are connected in series or not.. making sure you have connected them correctly. making sure not to have missed hooking up any wrong wiring. now having everything hooked up except the ground to battery post, put a test light between the neg.post of the batt. and neg. cable end. N O T E if there is anything drawing amps the light will come on. for instance a clock radio would to some point draw enought to poss. have a very dim/weak light. a headlight switch or sort would draw alot of amps and would light your test lamp bright. as would a direct sort in the system. if your batts are being drained, use the test light or a buzzer to elleminate the problem.. again take a volt test a assure 13plus volts. then start and check charging system. hope something here will help ya. if not email me.. gw
