85 Jetta 1.6 na diesel coupe. Had a battery that wouldn’t keep its charge and when I went to get new one they didn’t have the exact replacement but I got one that had a little more cold cranking amps. My diesel motor used to fire off on the first revolution and now you have to hold the key down for a bunch of revolutions. Obviously issue started with a battery change but could my glow plugs be going bad too?
I ask that question because it takes a long time for the glow plug light to go out now.
I’m going to get another battery but just curious if anyone’s experienced this. I’m new to diesels.
